User/ryanbod/fix unittests (#5191)

* Fixing PowerLauncherViewModelTest.cs.  These OpenConsole functionality was accidentlly removed in a merge conflict, which broke the build.  The build was fixed, but the unit tests didn't work.  034079b441 is the offending change.

* Color picker tests need to remove the ShellPage.DefaultSndMSGCallback on cleanup.

* Fixing casing that was updated in previous change.
