chainntnfs: use spent height as height hint if found

Browse Source 
Previously when deciding whether a UTXO is spent or not, we accept a
height hint as the starting block to look for the spending tx in the
rescan process. When it's already found spent before the rescan starts,
we will update the height hint to be the spent height, only if the
latter is greater. This means if the user-specified hint is greater than
the actual spending height, this UTXO will never be found as spent. We
now fix it by always using the spent height as the hint.
