Avoid triggering a full update when saving a qml file (mobile project)

Currently saving a qml file triggers a "folderUpdated" (due to the atomic save), that triggers an async update that reparses the project and updates the code models.
The cpp code model sees any update to the pro file as a "full" update and re-parses everything.
The qml code model from his side when a cpp file that exposes qml types is parsed triggers a full reparse of its model.
Thus lots of parsing
