Fixed issue #184

I added an additional testcase for the previously failing scenario.

Successful Jenkins run:
http://catrobatgw.ist.tugraz.at:8080/job/Catroid-custom-branch-test/459/

The one failing testcase passed here...
http://catrobatgw.ist.tugraz.at:8080/job/Catroid-single-UI-test/356/
... and on my Nexus 4 so i assume random failure.
