Limit the zip lookup test to behaviour the fix changes

The error for a template found in no search path is the same as on main,
so checking it tested behaviour this change does not touch, which is what
the review pointed out. The test still checks that a zipped Dag loads
templates from both its archive and a regular template_searchpath folder.
