Fix test caching

[b-rad-c]

If you run ./test.sh --use-cache from the templates/mapp-py folder you'll get this output:

:: Setting up TestMTemplateApp
  :: Creating tables in test dbs ::
E
======================================================================
ERROR: setUpClass (__main__.TestMTemplateApp)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/Users/brad/Code/medium-tech/mspec/src/mapp/test.py", line 287, in setUpClass
    raise RuntimeError('Need to fix cache with new auth system')
RuntimeError: Need to fix cache with new auth system

----------------------------------------------------------------------
Ran 0 tests in 0.155s

FAILED (errors=1)

because awhile ago the auth system was updated and broke the caching. The tests pass if you just run ./test.sh. This exception is throw in setUpClass method in test.py, we should only need to update this function and possibly create a couple helper functions in this file but we want to avoid a large rewrite.

requirements

• fix test cache system
• avoid large rewrite, if more than the above changes are needed simply explain the problem without making changes and then we'll assess the level of effort.
