Bug 10741: restore holdability of in-transit items on OPAC search results

In search results, one could not place a hold on an item in transit
and for loan (items.notforloan=0).  This appears when AllowOnShelfHolds
is allowed.

This patch repairs a regression introduced by the patch for bug 8975.

Test plan :
- Set AllowOnShelfHolds to on
- Create a record with a normal item : not lost, not withdrawn, not
  damaged, notforloan=0
- Index this record
- Perform a search on OPAC that returns this record (and others)
=> You see in actions "Place hold"
- Add this item in transit : /cgi-bin/koha/circ/branchtransfers.pl
- Re-perform the search on OPAC
=> You see in actions "Place hold" and item "in transit"

Bug 10741: reformat test for displaying place hold link in OPAC search results

To test:

[1] Turn on the syspref for enabling OPAC holds.
[2] Create an item and bring it up on the OPAC search
    results.  Run through the following possibilities,
    by changing the item, and verify that the place hold
    link in OPAC search results appears only when the item is

    - not lost AND
    - not withdrawn AND
    - not damaged (or is damged and AllowHoldsOnDamagedItems is ON) AND
    - the item is not marked not-for-loan OR
      the item has a negative notforloan value (e.g., it is on order)

    Note that it is necessary to reindex the test bib after making
    each change to the test item.

[3] Also verify that whether or not in the item is in transit does
    NOT affect whether the place hold link appears.
[4] Verify that there is no regression on bug 8975 (i.e., if an
    item is on order, that status should be displayed in staff client
    search results).
