proper cleanup of ecoren_con_server after ecore_events.

ecore_events are asynchronous and can be dispatched after the server
is deleted (ecore_con_server_del()). In this case, server will flag
"delete_me" and avoid doing double-free. When the event is dispatched
and the server is deleted, we still need to free resources and so we
need to call _ecore_con_server_free(). But we cannot do that by means
of ecore_con_server_del() since it will check "delete_me" flag and
will return.

This patch calls _ecore_con_server_free() directly when events are
dispatched and server is deleted. It fixes problems with
forecasts/weather modules exhausting file descriptors, a long standing
issue that bring problems with pam/desklock authentication.

Thanks to manio to point out #305 and testing.
