Now that we have turbo, we need to re-think some UX. When inviting a
user, it used to display a message at the top of the screen saying
"Invitation resent" at the top of the page. We keep the scroll positin
so admins working on the user page don't lose their place. This creates
a problem as the message is at the top of the screen and the admin has
no sense of any action having been performed.
So instead, we replace the resend invite button with text saying
"Invite sent" so the admin understands they were successful.
