lnchannel: persist error sent by remote peer into db

Browse Source 
If a force-close happens due to e.g. a feerate disagreement or an invalid signature, etc,
and the remote peer sends us an error, it can be useful if users can provide us with this error.
If the user does not have logging enabled when the error is sent, without this persistence it will likely get lost.
