REVISION SUMMARY
  When launching the touchpad kcm we see the following warning:
  
    Error on d-bus read of "supportedButtons"
  
  And the Gui shows "Error while loading values. See logs for more
  information. Please restart this configuration module".
  
  By extending the unit test for reading back the properties through DBus
  I noticed that it's not trivially possible to export QFlags to DBus. As
  the QFlags can be implicitly casted to int, the property is changed to
  an int value.

TEST PLAN
  Test case adjusted, did not pass prior to change, passes now.
