The Issue itself should be resolved, Still TODO: Remove Log.d() messages
and write automatic tests, .R import order
Added Test for the Issue, but it fails half of the time due to the 
screenshot not being saved or the thumbnail not loading correctly.
The issue should be resolved with this commit, still debug messages to
get rid of.

Important Change: Had to take the screenshot at the second frame instead
of the first in the render() method of the StageListener, because the
ScreenUtils.getFrameBufferPixels() method used to get the pixels,
returns an all white picture in ~1/5 trys and this was untestable.(And
not intended behaviour)
Cleaned up debug log messages and removed warnings
Temporary framebuffer debug messages inserted
