Fix not calling SetConfiguration on hfp/hsp endpoints before connected
Fix not calling SetConfiguration on hfp/hsp endpoints before connected

This cause some clients like PulseAudio to fail to find a proper
transport since connected state is send before transport configuration
is set.

To fix this now SetConfiguration is called early on when headset is still
in connecting phase, this matches sink/source where SetConfiguration is
also called before connected.
