Ensure start of call properties are propagated to RemoteConnection.

Some properties were not being propagated to a RemoteConnection when
a Connection is first created.  This can cause problems where the
Connection Manager is not aware of these property changes, especially if
they never change again during the lifetime of a call.

The extras set when a Connection is first created using the
RemoteConnectionService API would not be propagated to the
RemoteConnection.  This means that Telephony RAT reporting would never
happen if the radio technology never changes during a call.
