[android] Fix crash caused by unreferenced driver (#58)

Previously, if the user selected a per-game driver and that driver was
deleted from the global menu, it would cause a crash, it was because of
a mismatch between FileNotFoundException and NoSuchFileException. To
avoid the inconsistency I just made the check for if a file exists or
not to be separate.
