wallet2: fix rescanning tx via scan_tx
- Detach & re-process txs >= lowest scan height - ensures that if a user calls scan_tx(tx1) after scanning tx2, the wallet correctly processes tx1 and tx2 - if a user provides a tx with a height higher than the wallet's last scanned height, the wallet will scan starting from that tx's height - scan_tx requires trusted daemon iff need to re-process existing txs: in addition to querying a daemon for txids, if a user provides a txid of a tx with height *lower* than any *already* scanned txs in the wallet, then the wallet will also query the daemon for all the *higher* txs as well. This is likely unexpected behavior to a caller, and so to protect a caller from revealing txid's to an untrusted daemon in an unexpected way, require the daemon be trusted.
