Possible leak of SearchReplyProxy pointer

[dobey]

To resolve the issue of the search not timing out properly when completed, https://bazaar.launchpad.net/~unity-team/unity-scope-click/devel/revision/232 was made to call finished() on the search. However, it is still possible that the pointer may be getting leaked, by behind held somewhere, which is keeping the pointer in scope, and thus not finishing automatically.

This needs to be investigated, so we avoid leaking the pointer when a search is performed.
