Disallow multiple module() calls in a descibe block

[remcohaszing]

I have encountered the following type of unittest setup several times now:

describe('', function() {
  // ...

  beforeEach(module('myApp'));
  beforeEach(module('ui.router'));

  // ...
});

This typically indicates that the module is not setup correctly. The myApp module should have ui.router as a dependency instead.

It should be allowed to add exceptions (e.g. ngMaterial-mock or ngCordovaMocks)
