chore(modules): execute modules unit tests in one karma run

SauceLabs  is struggling to keep connecting and disconnecting
for each of the modules unit test runs. This commit puts most of
the module tests into IIFEs so that they can be run in one go.

* ngMock is still tested separately since unlike the other tests
it doesn't want to have a pre-built version of ngMock available.

* ngAnimate is still tested separately because it does some funny
things with globals that were difficult to isolate in the main modules
test run.
