Bug 14651: Koha::Item->effective_itemtype fallback to bib-level
In some situations (bad migrations, old bugs that introduced bad data,
people having bib-level itypes for ages and switching to item level...)
the user ends with undex itype values for items.
The current code, if the user has item_level-itype set, just returns
undef. It should fallback to bib-level. In order to avoid hiding the problem
a warning is raised.
To test:
- Run the regression tets:
$ prove t/db_dependent/Items.t
=> FAIL: tests fail.
- Apply the patch
- Run the tests again
=> SUCCESS: The tests now pass.
- Sign off :-D
