Fix mapCkbtcTransaction issue (#4091)

# Motivation

There was a typo in the "Confirmed" retrieval status in
`mapCkbtcTransaction`.
The test would have failed before of the error logging, but another test
mocked out the error logging and it wasn't reset.

# Changes

1. `vi.restoreAllMocks` in `beforeEach`.
2. Fix the typo.
3. Fix another test which started logging an error about the memo not
being decodable.

# Tests

updated

# Todos

- [ ] Add entry to changelog (if necessary).
