Fix QmlInspector to work properly now that QmlProjectManager

no longer uses LocalAppRunConfiguration. QmlInspector now uses
the qmlviewer started by QmlProjectManager instead of starting
its own, and clicking the Start Debug button within a QML
project will switch to QML Inspect mode and start the inspector.
