Android: Fix unnecessary clipboard data access

Android 12 introduced a notification which is shown to the user each
time the app accesses the clipboard via getPrimaryClip.
Currently this notification is triggered, even if we just want to check,
if some clipboard data exists.
So lets not get the actual data and instead use getPrimaryClipDescription
to check for the existence of the correct mime type in the clipboard.
