[Qt-creator] Using Qt Quick 1 code model instead of Qt Quick 2. (M324)

[Harri Pasanen]

With Qt Creator from 5.4.0 RC  I get squiggly underlines under QML 
elements and the tooltip in subject when I hover with a mouse.

I presume because of that the F1 help does not work.

Everything seems to run though.

What might be the cause this? 
https://bugreports.qt-project.org/browse/QTCREATORBUG-11328 describes 
the same symptoms, but I'm not using CMake.
