Bug 33074: Take ReservesControlBranch into account in opac-reserve.pl

Bug 33074: Take ReservesControlBranch into account in opac-reserve.pl

Test plan:
1. Set system preferences:
   - Disable OPACAllowUserToChooseBranch
   - Set ReservesControlBranch to "item's home library"
   - Enable UseBranchTransferLimits
   - Set BranchTransferLimitsType to "item type"
   - Enable canreservefromotherbranches
   - Disable IndependantBranches
2. Create two libraries: ITEM_LIB and PATRON_LIB
3. Set circulation rules:
   - Remove all circulation rules (DELETE FROM circulation_rules)
   - Set a default rule that allow some holds and with "OPAC item level
     holds" = "force". Allow "on shelf" holds for easier testing.
   - In the rules for ITEM_LIB, under "Default checkout, hold and return
     policy",
     - set "Hold policy" to "From any library"
     - set "Hold pickup library match" to "item's home library"
   - In the rules for PATRON_LIB, under "Default checkout, hold and
     return policy",
     - set "Hold policy" to "From any library",
     - set "Hold pickup library match" to "any library"
4. In "Library transfer limits" disable all transfers from ITEM_LIB to
   PATRON_LIB for an item type (let's say "BOOK")
5. Create a biblio with an item:
   - item type must be the same as in previous step ("BOOK")
   - home branch and holding branch must be ITEM_LIB
6. Create a patron at PATRON_LIB, give it a password so it can log in.
7. Go to OPAC, and login with this patron
8. Try to place a hold for the new item. You should be allowed to place
   a hold, but when doing it, no holds will be created.
9. Apply patch, restart Koha
10. Try to place a hold for the new item. This time the hold should be
    created
