Move 'create_spend_to_address' to wallet backend.
...
This required changing a bit about the relationship between
database errors and wallet errors, and opens up the possibility
of now simplifying the error situation a bit.

zcash_client_sqlite: Read rcm correctly from data DB after Canopy
...
ZIP 212 alters the note plaintext to store a seed from which rcm is
derived, rather than storing rcm directly. In the mobile SDKs we only
need rcm, so for post-ZIP 212 notes, we derive rcm from the seed and
store rcm in the data DB.
However, when selecting notes to spend, `create_to_address` was using the
transaction's target height to determine if Canopy is active, and parsing
the rcm value as the seed if so. This effectively applied a seed->rcm
derivation to all selected notes' rcms once Canopy activated on the
chain. As a result, the note commitments were incorrect, and thus the
anchors derived from the witness paths were also incorrect. This caused
two kinds of observed failures:
- If more than one note was selected, the builder would fail with
"anchor mismatch", as the note commitments would be effectively
randomised, causing the derived anchors to also randomise.
- If a single note was selected, the transaction would be built using
the randomised anchor, and then rejected when sent to the network.
The fix is to "pretend" in `create_to_address` that all notes are
pre-ZIP 212 notes. This works fine because we never need to serialize
back to the note plaintext while spending a note.
