lnwallet/channel: remove FeeUpdates when compacting logs

Browse Source 
When compacting the update logs we remove any fee updates when they
remove height is passed. We do this since we'll assume fee updates are
added and removed at the same commit height, as they will apply for all
commitments following the fee update.
