OZP-103: Write RPC API unit tests.

1. Fixed bugs where .only would run multiple tests due to testacular not recognizing different test names beyond a certain number of characters (i.e. 'publishes data between widgets' === 'publishes data between widgets using legacy calls').
2. Fixed bug where rpcContainerSpec communication tests would sporadically fail in Firefox due to widget 1 not finishing registering its RPC function prior to widget 2 trying to use it.
