Bug 19298: Placing a hold from a list at the OPAC should respect issuing rules

The issuing rule retrieve to know if a hold can be placed on a record of
a list is not correct.

Test plan:
0/ With item-level_itypes = item level
1/ Define a item.itype=BK and biblioitems.itemtype=CF
2/ Create a default rule to allow on shelf holds
3/ Create a specific rule for CF with on shelf holds="If any
unavailable"
4/ Add this bibliographic record to a list and view the list
=> Without this patch you will not see "Place hold"
=> With this patch applied you will see the "Place hold" button,
respecting the correct issuing rule

Followed test plan, patches worked as described.

Note: Just to clarify the test plan slightly in step 4 where it says you will not see 'Place Hold' it means to
the left of the 'Save to another List' link below the item availability
in the opac-shelves.pl page. Not the 'Place hold' button in the grey
page header box.
