Bug 6874: Catch warnings for clean tests.

Bug 6874: Catch warnings for clean tests.

I hate noisy tests, so I cleaned them up.

MEGA TEST PLAN
--------------
git checkout -b bug_6874 origin/master
git bz apply 6874
-- yes, it should all apply smoothly.
I intentionally restored an old backup from a couple months ago to force the upgrade.
staff client:
-- upgrade
-- login
Koha administration
MARC Bibliographic framework
MARC structure (for BKS)
Search for 856
Subfields
Edit (for u)
Other options
Plugin: upload.pl
Save changes
Search the catalog tab
{choose a word, any word. I used fancy, because I knew we had a cookbook}
click first link
Edit
Edit record
8 (that's the tab name)
click the name for 856
scroll down to u and click the plugin icon
-- Correctly got a configuration error message.

At a command prompt:
vi ~/koha-dev/etc/koha-conf.xml
/enable_plug
-- add in:
<upload_path>{appropriate path. I used /home/mtompset/uploads}</upload_path>
:wq
mkdir {appropriate path used}
-- I even added some subdirectories
sudo chown -R -v www-data.www-data {appropriate path used}

Back in staff client:
click the plugin icon again
-- this time an upload screen pops up
click the 'Upload file' button
-- message about no file or destination
browse for a file, select one
click the 'Upload file' button
-- message about no destination
click the 'Cancel' button
click the plugin icon
click a destination radio button
click the 'Upload file' button
-- message about no file
browse for a file, select one
click the 'Upload file' button
-- message about success
click the 'close' button.
-- the text box has been filled in with a nice URL
click the plugin icon
click cancel
click the plugin icon
click delete
-- the test box should be blanked, and a success message given
click Close
-- reupload a file properly
click the plugin icon
click delete
click upload file
browse for a file, select a destination, click upload file
click close on success message
click 'Clone this subfield'
click the second plugin icon
click delete
click close
click the first plugin icon
-- Nice error message about a URL which points to nothing.
click cancel
In the second 856$u type in a URL (eg. www.google.com)
click the second plugin icon
-- this jumps immediately to the upload screen, but does not give an error message, because the URL does not have opac-retrieve-file in it.
click save (we need to save the bibliographic record)

In OPAC:
search for the same word (I used fancy)
find the entry you just updated with links
click the two links. The dangling entry should give you a 500 error, and the other link should work just fine.
get back to the detail page

In staff client:
edit
edit record
8
change the 856$u to a valid file in the first link.
save

In OPAC:
refresh the detail page, and click the first link again
this time it should get downloaded nicely.

From a command line:
prove -v t/db_dependent/UploadedFiles.t
perldoc C4::Biblio
perldoc C4::UploadedFiles

One more round of tests tomorrow, and this should be ready. :)

Tested on top of 5010

Followed mostly mega test plan, seems to work :)
Can upload, delete, modify, etc
Test runs Ok
No koha-qa errors

I view this as valuable addition, dangling since 2011!
As with 5010, I consider this can be pushed (for 3.22)
and we can fix anything wrong later.
