Bug 12918: fix failing test case

A bug in a test case causes test case failure. It also required a
database, so I'm moving it out of the way.

Test plan:
1) prove -v t/db_dependent/Templates.t
   -- bombs!
2) apply patch
3) prove -v t/db_dependent/Templates.t
   -- works!

Good catch Robin, it didn't fail in Perl 5.18 so didn't notice the mistake.
