spurious `TransactionManagementError`s

[davedash]

I am getting "TransactionManagementError: This code isn't under transaction management" for some of my tests...

Using git bisect:

4300764d9dcb05487a33127760bc3d658369b97d is the first bad commit

Factor Jinja- and cache-machine-specific stuff out of FastFixtureTestCase, and make TestCase a thin wrapper around it.

Anybody who uses TestCase should go fast for free.

The net result is I need to pin mozillians at a certain commit for this to work.
