Description
To reproduce:
1. Apply this patch: https://codereview.qt-project.org/c/qt-creator/qt-creator/+/348559
2. Load creator project into creator and open any qml file
3. As soon as you see the "Switch session or shutdown now!" printout, close creator (or switch the session). It should crash.
The reason is that SemanticHighlighter::rerun() starts a new task, and this task is not stopped on shutdown or on session switch.
