Portfolio member domains list missing domain invites for existing members

[rachidatecs]

Current Behavior

The list of domains on portfolio domains management pages gets different lists for members and an invites.

If it's an invite (ie email), we retrieve the domains from the domain invitations that intersect the email and portfolio.

if it's a member (ie User), we get the domains from the user domain roles that intersect the user and the portfolio. In this case, we are missing any potential domains that user is invited to.

Expected Behavior

The domain list for a member should include any domains that member is invited to.

Steps to Reproduce

1. Go to Django admin domain invitation table
2. Add a domain invite to an existing portfolio User.
3. Check the domains list for that user.
4. It does not include the domain added through the invite.

Environment

No response

Additional Context

Suggested solution:
When going to the Domain assignment tab, if the user is an existing member, then we retrieve any “invited” domain invitations and generate the user domain roles. This is done prior to getting all user domain roles for the page, thus when we query for user domain roles we should then have all domains this person can manage.

Removing refinement: I verified this is a real issue, and added a solution. Realistically, this should only happen if an analyst/superuser creates domain invitations for an existing user instead of user domain roles AND someone happens to visit this page before the "invited user" logs in to retrieve their invitations
