QDS marks project dirty when opening

Steps to repro:
1. Open project hyperreal from the Qt git. QDS opens but you can see the project "touched"

2. See that Screen01.ui.qml is 'dirty':

3. Save to see what is changed and look from the git:

% git diff WebinarDemo/content/Screen01.ui.qml

diff --git a/WebinarDemo/content/Screen01.ui.qml b/WebinarDemo/content/Screen01.ui.qml

index 191e9a7..78c28a0 100644

• • • • a/WebinarDemo/content/Screen01.ui.qml*
