Jason Simmons 5e057b2885 Some cleanup of the Sky analyzer script
* If no source path is provided, then run the analyzer on the Sky unit tests
* Fix the filter for errors found in pub cache packages
* Generalize the filter for the analyzer's "xx errors/warnings/hints found" status message

Also fix a test that caused a warning in the analyzer.
