Updated module name in test suites

There is no real impact with this change other than more consistency.
Named all functions for more detailed stack traces

This is an entirely developer-focussed change to help make stack traces
a little more clear.
Removed unnecessary source code

There's no reason to keep commented out code around even if we plan to
reimplement that functionality in the future. There's even less of a
reason to keep using more verbose angular injection array-based
convention if we're not actually injecting anything.
