Patch for the MaemoConic device

[Sergio Villar Senin <svillar igalia com>]

This patch properly disconnects the "connection-event" signal in the
Maemo Conic device. We're trying to disconnect this signal from the
TnyDevice instead of from the Conic connection. I think this could be
the source of lots of SIGSEV's we're seeing when finalizing.
