Debugger: Avoid "Could not connect ... QML debugger" warning for mixed debugging

There's a race condition between the QML Engine trying to connect after the app printed
"Waiting on debugger port ...", and any possible Cpp breakpoints stopping the app.
Therefore, don't annoy the user with "Could not connec to QML Debugger" warnings
while the Cpp debugger is stepping.
