Subject: [PATCH] wtxmgr: ignore ErrBucketNotFound error upon locked outputs
 bucket deletion

This error would be seen when an old wallet that has yet to update is
performing the latest wtxmgr migration. It's possible for the locked
outputs bucket to not exist if outputs haven't been locked before, so we
should its deletion correctly.
