tablet-v2: fix merge commits and test again

Browse Source 
There were a few issues after rebase, that the merge algorithm didn't
throw at my face:

wlr_output did a check on the actual role, not a string anymore, so that
had to go to allow tablet-v2 to set cursor surfaces.
A few L_DEBUG/L_ERRORs were still around
There was a user-after-free in tablet-group free()ing, probably after
insufficient testing from a previous feedback pass
