Bug 18525: (bug 14828 follow-up) FIX ordering from suggestion when item-level_itypes = biblio

When ordering from a suggestion with item-level_itypes = biblio the app
crashes with
Template process failed: undef error - The method selected is not
covered by tests! at /home/vagrant/kohaclone/C4/Templates.pm line 121.

C4::ItemTypes->all did not set a selected flag. The item type is only
display when ordering (and not modifying an order).
The flag is never set, the test can be removed.

Test plan: Confirm that the error is gone
