Issue Summary

When an email is firstly invited as a customer and then as an Atlassian Account, they will end up with duplicated accounts. Customers in that condition will be asked to "Login with single sign-on" because of the Atlassian Account. If the Atlassian account is then disabled, Jira will still ask the user to "Login with single sign-on" even if the only active account now is the portal only one, which authenticates directly in Jira with username and password.

Steps to Reproduce

1. Create a portal only account;
2. Invite the same email as an Atlassian Account;
3. Disable the Atlassian Account;
4. Try to log in to the customer portal.

Expected Results

Jira will present the password field since the Atlassian Account is disabled and the email is now a portal only account.

Actual Results

Jira still asks the customer to "Login with single sign-on", but since the Atlassian account is disabled, they won't be able to log into the portal.
