Bug 29083: Update article requests-related Koha::Patron methods to use relationships

This patch makes Koha::Patron->article_requests use the underlying DBIC
relationship and _new_from_dbic instead of a plain search. It also
refactors 'article_requests_current' and 'article_requests_finished' to
use ->article_requests, as well as the new methods introduced by bug
29082 for filtering.

No behavior change should take place.

To test:
1. Apply the unit tests patch
2. Run:
   $ kshell
  k$ prove t/db_dependent/Koha/Patron.t \
           t/db_dependent/ArticleRequests.t
=> SUCCESS: Tests pass!
3. Apply this patch
4. Repeat 2
=> SUCCESS: Tests pass!
5. Sign off :-D

Bug 29083: Unit tests

This patch adds missing tests for Koha::Patron->article_requests and
moves (and extends) tests for 'article_requests_current' and
'article_requests_finished' that were originally in ArticleRequests.t
into Koha/Patron.t as we now do.

To test:
1. Apply this patch
2. Run:
   $ kshell
  k$ prove t/db_dependent/ArticleRequests.t \
           t/db_dependent/Koha/Patron.t
=> SUCCESS: Tests pass!

Bug 29083: Fix OPAC listing of article requests

This patch makes the OPAC template reuse a precalculated value for the
active article requests for the patron (and its count).

The original code relied on the methods returning a list, which is not
the case for _new_from_dbic until bug 28883 is pushed.

This patch fixes that.

Note: there was an odd behavior when ArticleRequests was enabled but no
active article requests were present: the tab wasn't rendered but the
'empty table' with the 'You have no article requests currently.' message
was displayed below the Checkouts tab. I'm not sure that was caused by
this patches, or other. Fixed on this patch.

To test:
1. In the OPAC, go to 'your summary'
=> FAIL: Things don't show for article requests
2. Add some article requests and repeat 1
=> FAIL: Something's wrong there
3. Apply this patch and repeat 1
=> Yes! Things show correctly!
4. Cancel all your article requests
=> SUCCESS: Things render as they should
5. Re-enter the 'your summary' page (to force re-rendering)
=> SUCCESS: Things render correctly for empty article requests

Bug 29083: Remove article_requests_finished and article_requests_current

This patch removes those methods that are not really needed. Templates
are adjusted to use the expected combination of
->article_requests->filter_by_current.

To test:
1. Apply this patch
2. Visit a patron with article requests
=> SUCCESS: All works
3. Run:
   $ kshell
  k$ prove t/db_dependent/Koha/Patron.t
=> SUCCESS: Tests pass, less tests.
