Bug 22140: Use of EasyAnalyticalRecords pref in search

Like Bug 20702 defined GetHostItemsInfo does nothing if EasyAnalyticalRecords pref is disabled, there are other places where code must be dependant on this pref.

Test plan :
1) Build an analitical record with 773$0 and $9
2) Enable EasyAnalyticalRecords
3) Don't apply patch
4) Go to OPAC
5) Perform a search that displays the record, check there is the linked item
6) Open record detail page, check there is the linked item
7) Apply patch and redo 5) and 6)
8) Disable EasyAnalyticalRecords
9) redo 5) and 6), you should not see the linked item
