Bug 24412: Attach waiting reserve to desk

Bug 24412: Attach waiting reserve to desk

When an item is checked in and marked 'Waiting' or already 'Waiting'
and there is a desk attached to the session, the item is marked
waiting at the current desk of the current library.

The information is displayed on the OPAC and on the intranet. The
patron can then know at which desk he can retrieve his document.

Desk Management (Bug 13881) is now useful.

Test plan :

1. apply Bug 24201
2. $KOHA_PATH/installer/data/mysql/updatedatabase.pl
3. Check out some document to someone
4. make another one reserve this document
5. check in the document
6. you can see the document is attach to the current library
7. create some desks and attach one to your session (see Bug 13881 and
Bug 24201)
8. cancel the preceding reserve and redo steps 3 to 5
9. you should see the document is waiting at the current library and
current desk on:
  a. the intranet document request page
  b. the intranet borrower holds tab
  c. the item list where the document is listed on the bibliographic
    details
  d. the borrower's OPAC holds tab.
