decodebin3: Reset main group id on PAUSED->READY state change

The main_input stream-id would not get reset when going to READY state.
This would cause warnings when trying to reuse the same decodebin3, since
you would get a new STREAM_START event with a new stream-id, which would
collide with the now stale stream-id
