Fix password change/reset not immediately invalidating other sessions (#12928)
While making browser requests in the other sessions after a password
change or reset does not allow you to be logged in and correctly
invalidates the session making the request, sessions have API tokens
associated with them, which can still be used until that session
is invalidated.

This is a security issue for accounts that were already compromised
some other way because it makes it harder to throw out the hijacker.
