C++: Fix duplicate items in C++ completion for Qt methods

Browse Source 
In the old code completion engine items were created on the stack
and passed around by value. With the refactoring of the code assist
API they became heap objects manipulated through pointers. This
patch fixes one reminiscence not caught during the refactoring
in which the same actual pointer was being used more than once to
be appended on the list.
