tracker/pt: workaround unexplained leak

Somehow, using unique_ptr causes a leak at destruct time. The stored
pointer isn't freed. It works perfectly fine with shared_ptr.

It seems I'm doing things correctly with a move constructor for
unique_ptr in the Tracker_PT class, as well as the pointer
initialization ctor in `module.cpp'. Who the hell knows what's happening
behind the scenes.
