The navigation bar dismissal animation caused by "activity finish"
should be invoked in some cases immediately when the user
cancels authentication. Add a "early user cancel" message
for ConfirmDeviceCredentialActivity to subscribe to. This
message is sent immediately when the user invokes a back gesture or
cancels authentication.
