I tried the branch on 3.16.2 of WPR, can see that
1- nothing was mentioned about force-wp-mobile now with smoke test

Error : Warning: The 'force-wp-mobile' plugin could not be found.
Error: No plugins uninstalled.

is not there now but instead Error:, do we log this in any case or just after having error?
2- only 1 scenario failed due to errors in debug.log , probably related to #54
