There's no reason to keep a msg after it was sent. Before this patch we
had edbus_service_signal_send() unref'ing its msg and all the others
not. Also, several users (particularly the edbus_proxy_send() ones) were
forgetting to unref the msg.
This patch makes all these methods unref the message after it has been
succesfully sent:
- edbus_connection_send()
- edbus_object_send()
- edbus_proxy_send()
- edbus_service_signal_send()
