Git: Fix resolving top level for non-existent sub-sub-directory

Browse Source 
When a directory is renamed, and it has sub{sub-}*directories, executing
git blame on a file in the subdirectory -> Blame Revision (or parent) for
the file in the previous name -> Show failed because it couldn't determine
the top level directory.

You can test by opening qmakeprojectmanager/wizards/filespage.cpp and
blaming one of the lines that had it as qt4projectmanager/...
