C++: Fix dangling IDocument* in CppCompletionAssistProcessor

Browse Source 
Steps to reproduce the crash:
 1. Open some long file, e.g. botan.cpp
 2. Trigger completion and close editor immediately

The IDocument pointer was only used to reference the file name. Instead
of passing an IDocument* to the IAssistInterface, pass the file name.
