Update Test Cases

[jtoman]

We had a lot test cases that did a pretty good job of ensuring that changes made to Rtc did not break functionality. These test cases are very old and don't cover a lot of the newer features of Rtc. In order to make Rtc easier to develop we should update (or remove where appropriate) old test cases and add in test cases for new features.

There has been great progress on this ticket. We need to add tests for proxy objects, i.e. ensuring that they continue to maintain type checking across function calls, etc.
