QML debugger: Don't crash when creating objects on engine destruction
You can create further objects while the QML engine is being destroyed.
The debug service is not interested in those because they will be rather
short lived anyway.
Task-number: QTBUG-62458
Change-Id: If5395ef058268e0e956d159bc636495da1c0c98f
