Autopilot tests (try to) stop maliit-server

Since revision 168 in lp:ubuntu-calendar-app, the following code was added to the setUp() method of the base test case for autopilot calendar app tests:

        #turn off the OSK so it doesn't block screen elements
        if model() != 'Desktop':
            os.system("stop maliit-server")
            #adding cleanup step seems to restart service immeadiately
            #disabling for now
            #self.addCleanup(os.system("start maliit-server"))

This feels and looks wrong. If we prevent the OSK from appearing, then we’re not really testing the app in normal conditions, are we?
Besides, it simply doesn’t work when I try to run the tests on my Galaxy Nexus, all the tests fail.

Finally, the commented out cleanup doesn’t work because addCleanup expects a function object, not a call. So it should be something like: self.addCleanup(lambda: os.system("start maliit-server")). But that’s an unimportant detail considering the points above. This should be removed, and the edit event test fixed in a proper way.
