QML debugger cannot deal with multiple QmlEngines
Steps to reproduce:
(1) Create a QML Application using the wizard
(2) Enable QML debugging in run settings
(3) Test QML debugging (it works)
Add this code to main.cpp
(5) Test QML debugging again (it does not work anymore)
The first break point seems to be hit, but Qt Creator does not show the correct location. Continuing does not work. The QML application hangs.
