If custom theme is not found, autopilot tests should bail out, as they will fail

[Chris Wayne]

Currently in the touch_custom test suite, the ubuntuuitoolkit hangs because it has trouble finding the theme (due to the way autopilot launches the tests). The tests should already be not running if the theme is not found
