Subject: [PATCH] Don't disconnect the same device before connecting.

We Pair: Remote device sends incoming connection, we get connected.
We get BondingState change and we connect.
Settings app disconnects connected profiles and then connects
without checking whether we are disconnecting the same device itself.

How was it working before ? Settings app used to queue all
commands. The disconnect followed by the connect would work
but unnecessarily disconnect and then connect.
With the queuing moved to framework, the connect fails
since the disconnect status has not been broadcasted.

Settings app shouldn't be disconnecting connected profiles.
That logic should reside in the framework. There is an open bug
and when the new APIs get implemented this will get removed.
