User switcher: hooks up broadcast receivers.

This was a missed part of the feature set. When switching to the guest
user, a notification is meant to be set shown. Hooking up the broadcast
receivers into the GuestUserInteractor achieves this and also shows up a
"resume session?" confirmation dialog, which is what the failed test in
the attached bug was looking for.

Fix: 256835620
Test: "Welcome back" dialog shows now when I switch to guest. Also the
notification shows up.
