channeldb: bucket not found during .Wipe() is no longer an error

Browse source 
This commit changes the current behavior around channeldb.Wipe().
Previously if a channel had never been closed, and a wipe was
attempted, then wipe operation would fail and the transaction would be
rolled back.

This commit fixes this behavior by checking for bolt.ErrBucketNotFound
error, and handling the specific error as a noop.
