Subject: Fixing #2250 - Missing templates throw a helpful error

This changes the behaviour of template searching a bit -
we previously usually returned a file name, whether the template
existed or not.  Now we only return a path if it
exists.

Refactoring a few of the the tests for TemplateWrapper, also.
