Clang Code Model: Possible tool tip bug when project is a library.

1. Create a subdirs project
2. Add executable subproject
3. Add library subproject

When Clang Code model is enabled I get a strange tip that looks like an error/bug (see attached the screenshot) when I type qDebug() <<. This error usually appears when I start editing the document. If I close the project and reopen it - the proper tip for qDebug() is displayed.

I enabled Clang Code model only recently so I haven't noticed yet if the reported issue is wide spread.

I have attached a sample project.
