quickfix for SetSizeToBrickTest

don't know why, but test passes if started in ScriptActivity; when
starting in MainMenuActivity, getPrivateField did return the wrong,
outdated value
fix test in ProgramMenuActivityTest

testTitle should be more stable now; failed on Jenkins from time to time
fix test in ScriptActivityTest

since testproject only has one sprite, click on costumes failed;
instead a click on backgrounds has to be performed
fix test in ProjectActivityTest

testRenameSpriteDialog failed; robotium clickes on rename to rename a
sprite via context menu; click failed because spritename also contained
the term rename
refactor SoundRecorderTest

* test failed because prepareRecording was messed up
* refactor method name - no orientationchange is performed while
recording
