fix DeleteDialogTest

* adapt test to run with actionbar navigation
* add method to UiTestUtils to change from one fragment to another with
spinner in Actionbar
fix SoundRecorderTest

adapt test to run with new Actionbar navigation
quickfix for ProgramMenuActivityTest

* fix Nullpointer that happened from time to time when Activity not
ready
fix ProjectActivityTest

* add waitForFragment - missing call could lead to failing testcases
from time to time, if fragment is not loaded, but actions on Activity
are performed
* adapt testOverFlowMenuDelete and testOverFlowMenuRename - goBack does
not trigger the action event any more; a click on ACCEPT_IMAGE is needed
fix ScriptFragmentTest

use UiTestUtils method to get correct Listview (Index 1 with new design)
fix SoundFragmentTest

* increase playing time of soundfile
* adapted index of Imagebutton (0 recycle, 1 actionbar overflow)
fix test in ScriptActivityTest

clicks were too fast; accurate timeout is needed
