Our forms should rely on role IDs for displaying user information on the
portfolio page. This way they are decoupled from user table data and can
eventually rely on invitation user data where an invitation has been
sent but a user does not exist yet.
In order to place modal forms in other places on the page (so that forms
are not nested) it's necessary to move MultiStepModalForm links out of
the component. They just need to refer to the correct modal.
This PR also makes changes to ensure that the active modal is being
unset everywhere correctly when a modal is closed.
