test(modules): fix module tests which got disabled by ngMobile

When ngMobile was merged in, we accidentaly included angular-scenario.js
in the test file set for modules. Loading this file overrode jasmine's
`it` and `describe` global functions which essentially disabled all of
~200 unit tests for wrapped modules.

This change refactors the code to run the wrapped module tests.

I had to extract browserTrigger from scenario runner in order to achieve
this without code duplication.
