Investigate issue of users not being in any organizations

[anaelizabethenriquez]

The comment below, from #943, outlines a problem with a user not receiving an OA reminder email because they are not in an organization in RMD. In theory, everyone who has an RMD account should (at a minimum) be in the overarching "The Pennsylvania State University" organization, because anyone who can have an RMD account should be a PSU affiliate (or have been one in the past, in which case they'd have an Inactive status).

If needed, we could solve this by changing the database query that leads to OA reminder emails, so that being in an organization is not a prereq for these. Better, IMO, would be to fix the underlying data and whatever process is leading to Active users not being in any organization.

@anaelizabethenriquez There isn't a view for admins to see who is queued up for an email, but I can check from the backend. This user is not listed to receive an email. It appears there's an issue with our database query to determine who needs an email. If the user is not part of an organization, they get filtered out. This is the case for this user — no organization. Adding this user to an organization should fix the problem in the short term, but we may want to open an issue to fix the database query. That's assuming we want oa notification emails going out to users not associated with an organization.

Also, we'll probably want to figure out why this user is not associated with an organization.
