Code review comment for lp://staging/unity-scope-click/devel

There seems to be an issue with performing a search by typing into the search entry at the top of the screen, where the spinner that shows up in the entry during the search, never goes away, despite the results having been pushed to the dash. This is related to the switch to using Index::search() in query.cpp. Attempting to add a call to searchReply->finished() when the search was finished, seems to cause a crash. It seems like the pointer is being held somewhere, but I'm not sure where.
