QML profiler has broken compatibility

Since the addition of the QtQuick3D events, the following problems can be observed:

• Many of the QML profiler tests in Qt Creator are failing.
• If you profile an application built with a version of Qt that doesn't support the QtQuick3D events using a Qt Creator that does suppor them, you get inconsistent data for the JavaScript and QML categories.

I haven't tested the other way around (old Qt Creator and new Qt), but I suspect that also breaks in some way.
