Inline `VerificationRequest.{invalid,ready,started,done,cancelled}` (#11013)

* Inline `VerificationRequest.{invalid,ready,started,done,cancelled}`

These methods are all just shortcuts for checks on `phase`, so let's get rid of
them

* update test

* Add some more tests

* even more coverage

* fix tests
