Bug 32268: Prevent XSLT.t to fail randomly

Can't call method "itemnumber" on an undefined value at /kohadevbox/koha/Koha/Recall.pm line 343.

We should set item_level and not let TestBuilder pick a value.

This may have been caught (make it more obvious) by the recent change to
TestBuilder for boolean (Bug 32030: fix test builder for boolean)
