Fix resend verification email logic

There's a couple of states this partial can be in

* Verification email not sent to the provider
  - When the claim was flagged as a duplicate so we didn't send the
    email on claimant journey completion AND and admin is yet to
    manually send the verification email by clicking the button

* Initial verification email sent to the provider
  - The claim was not flagged as a duplicate so the initial email was
    sent when the claimant journey was completed

* Email sent by the admin
  - The claim was flagged as a duplicate but an admin has now clicked
    the send email button

To make the view a bit less confussing we've pulled out a partial for
the provider verification completed and uncompleted states.
