d2d-conv-manager: initialize dbus connection before dbus call

Bug is detected when UTC executing for line coverage.
When we call conv_service_get_connection_state(), there is a CRASH.
In this case, d2d API is calling dbus call without dbus connection init.
So, we add dbus connection init before dbus call.
