Right now this tries to create "fake" enrollments for visibility
purposes if you have a user that is visible due to their account admin
status, but that doesn't work if that account admin has no enrollments.
Rather then trying to dress this up in a real enrollment type,
for account users I'm just using the type of "FakeEnrollment" and
letting that carry it through. It removes an extra query, and makes it
so that account admins can still receive messages without having to
enroll in something.
TEST PLAN:
1) Create an account admin
2) In the api, attempt to send that admin a conversation message
3) The response should not be a 400 "invalid", but should instead
be allowed to send to that admin
