* Removed redundant configureHostInfo
It was only used to set the Kodi backend version which is also
set using setKodiMajorVersion.
* Removed unused annotations and throwables
* Improved robustness of SlideUpPanelTests
Replaced explicit sleeps with the waitForView action.
Fixed issue in waitForView action as it required the UI
to be idle which is mostly not the case for the bottom
panel with the progress indicator.
* Improved robustness of eventserver
When eventserver handles a wrong payload this should not crash
but simply show a log message and let the actual test fail.
Refactored MusicListFragment and PVRListFragment to use AbstractTabsFragment
Fixed scrolling in a nested scroll view using espresso
Fixed issue with setting and checking Kodi major version
* Added two abstract methods setSharedPreferences and
configureHostInfo to allow test classes extending
AbstractTestClass to set preferences or change the host info.
* Implemented a mock event server to test event server commands
* Implemented a handler to handle JSON input events over HTTP
