Ensure user is created/registered with an organization as system assumes that now

[tonysurma]

expands on #683

Need to verify that if you register/create a user interactively it requires an organization to be picked. Without that you would get the same issue we saw in #683

this means requiring the choice of an organization at registration

I check the azure site and if you don't select an organization. You receive an error.
