Bug 24295: Remove GetTransfers from C4/Search.pm

This patch removes the final use of GetTransfers from C4::Search.

Test plan
1/ Perform a search that will include results for some items that have
transfers of various states assigned to them
2/ Check the results match expectations (before and after applying the
patch should look the same)
3/ Signoff
