Add missing 'final's
NessUUID: Riefy error-handling so that we always print the full UUID string, regardless of where the error occurs.
We previously were not printing the whole string when getNibbleFromChar failed, so if we got
a UUID that was invalid because of a bogus character (as seen in BK-1311), we had no way
to know what the full UUID was.
