Ensure Subkeys are verified (#12155) (#12168)

Browse Source 
Backport #12155

When attempting to verify subkeys the email address verification step
requires checking the emails however, these emails are not stored on
subkeys but instead on the primary key.

This PR will obtain the primaryKey and check against these emails too.

Fix #12128
