Bug 33032: Fix alternate holdings in staff interface search results

Bug 33032: Fix alternate holdings in staff interface search results

If system preference AlternateHoldingsField is used, one can see a display in OPAC search results.
This display does not appear in staff interface search results anymore.

Test plan :
1) Enable feature with system preference 'AlternateHoldingsField', ie 852abc
2) Edit a record to add some datas in field 852
3) Perform a search in staff interface
=> You see the alternate holdings datas
