wtxmgr: only remove entry for specified spending transaction 
In this commit, we address an issue with the wallet store where it'd be
possible for us to keep lingering unconfirmed transaction entries for an
output that has been spent by a different, confirmed transaction. This
was caused due to us removing all spending transaction entries for a
given output when removing conflicts. Since all of the entries would be
removed, we weren't able to retrieve the hashes of the remaining
spending transactions to remove their records as well. Instead, we
propose to only remove the entry for the specified spending transaction.
