wallet: bugfix, load wallet with an unknown descriptor cause fatal error
If the descriptor entry is unrecognized/corrupt, the unserialization fails and
`LoadWallet` instead of stop there and return the error, continues reading all
the db records. As other records tied to the unrecognized/corrupted descriptor
are scanned, a fatal error is thrown.
