Root Cause

All accounts in Quay must have unique e-mail addresses and usernames. The issue here is that there exists a user under e-mail in Quay's db. Logging in with a user with the same e-mail address will not work because users are not connected via a special table in Quay's db and Quay will perceive logging in via that button as though a new user is coming in. Quay will then check if the e-mail address is unique and will find that it is not and will error out.
