Re-enable ViewCommandHandlers tests

This is for #7420 

I can run all Integration Tests on Windows 7 in brackets-shell **master** branch (*not* CEF 2171), so we might be able to just re-enable these. These also pass on Mac OS X 10.8 (but that was never a problem before).

@JeffryBooher Verify that the ViewCommandHandlers tests now pass for you when running all Integration tests
