wallet: Avoid leaking locktime fingerprint when anti-fee-sniping
Cherry-picked from: fa48baf23

Conflicts:
- Missing chain().lock(), moved assignment until after locking
  cs_main.
- Different structure and version of test framework required:
  - Different block heights
  - Different way of documenting test steps
  - Removal of wallet check, our tests don't run without a wallet
