Bug 21800: Check the correct framework for the repeatable tag

This depends on the framework parameter. Which should be added back to
the call in C4::Items.

Test plan:
[1] Mark in Default framework one subfield A repeatable and B not repeatable.
Go to item editor. (Work on a biblio in Default framework.)
Check saving and reopening these subfields with VAL1 | VAL2.
Subfield A should be cloned, B should be glued as entered.

[2] Mark in another Framework A not repeatable and B repeatable.
Change framework for this biblio.
Go to item editor again. Reopen item. Behavior subfields in reverse?
