Just so that other reviewers know: this patch was discussed in irc, and
Fr?d?ric agreed to fix the bug in another way:

- Create a new hook in pa_bluetooth_transport:
PA_BLUETOOTH_TRANSPORT_HOOK_NREC_CHANGED.
- The hook is fired by bluetooth-util.c when the transport's NREC
property changes.
- module-bluetooth-device.c won't listen the PropertyChanged signal of
MediaTransport anymore. Instead, it will use the hook in
pa_bluetooth_transport to get a notification when the NREC property
changes, and update the sink or source proplist accordingly.
