tests: Check that a verify operation can be immediately restarted

This excercises the path where we early-report a result and the
VerifyStop call must wait for the operation to complete intenernally.

Note that this test cannot fail right now due to the FpImageDevice
internal code still trying to hide the deactivation delay internally.
