mod_invites_register_api: Use set_password() for password resets Previously the code relied on the (weird) behaviour of create_user(), which would update the password for a user account if it already existed. This has several issues, and we plan to deprecate this behaviour of create_user(). The larger issue is that this route does not trigger the user-password-changed event, which can be a security problem. For example, it did not disconnect existing user sessions (this occurs in mod_c2s in response to the event). Switching to set_password() is the right thing to do
