[Qt-creator] Code model / static analyzer with changed working copies incorrect

[Wiebe Cazemier]

Hi there David, 

11.0.2 indeed picks up changes again when I save, but it's still not as good as the older QtCreators, which simply didn't need saving at all to always have an up-to-date code model. 

Regards, 

Wiebe

> Tested versions: 10.0.2 and 11.0.1, installed with maintenance tool.
