If a process tries to register a profile implementation that is already
registered, RegisterProfile should fail.
This should help address issues when two instances of PulseAudio are
running at the same time, and the second instance tries to register an
audio profile implementation that has already been registered by the
first instance. Two situations where this may happen is when more than
one user is logged in, or during the transition between the GDM session
and the user session, when PulseAudio gets started on the new session
before the old session has been fully terminated.
