Bug 19832: Don't fill holds in SIP/Transaction/Checkout.pm

AddIssue already checks for holds in the item being issued and deals with them

The sip code, additionally, does not consider that multiple holds per bib
is allowed

To test:
 0 - Apply only first patch (unit tests)
 1 - Place two holds for a patron on a bib
 2 - Checkout that item via sip_cli_emulator
 3 - Note all holds are cancelled/filled
 4 - prove -v t/db_dependent/SIP/Transaction.t
 5 - it fails
 6 - Apply second patch
 7 - prove tests, all green
 8 - Place two holds on a single bib for one patron again
 9 - Checkout the item via sip_cli_emulator
10 - Only one holds is filled
