QmlJSDebugger: Fix crash when stopping debugger

Browse Source 
The destructor of QmlAdapter deletes the QDeclarativeDebugConnection,
which in turn results in status changes to the QmLJSInspectorClient. This
again leads to QmlAdapter::logServiceStatusChange() being called for the
already half-destructed object ... break this change by guarding the pointer
to QmlAdapter in QmlJSClientProxy.
