Fix the Djblets utils module tests on Django 1.7+.
Review Request #7421 — Created June 13, 2015 and submitted — Latest diff uploaded
The utils module had a number of template-related tests that no longer work in Django. We were digging into the internals, trying to construct tags manually, instead of through a template string. Now, we're using template strings, restoring compatibility across all versions. There was also a docstring being executed in the django.core.files.locks compatibility module, which we didn't want to execute. This has been removed.
Utility unit tests pass on Django 1.6 and 1.8.
