Additional context
Add any other context about the problem here.

Start by reproducing the reported salt-call saltutil.wheel key.accept invalid-minion command and trace the wheel.key.accept entry point. Inspect how it determines success for a nonexistent minion and locate the related test area, if present. Done means the command no longer reports success when no key was accepted and regression coverage verifies the result.
