To show the object string id's, the debug protocol is used to get them.
The problem is that the required methods in QDeclarativeContext(Data)
are not exposed, and it's too late to do it for 4.7.0. Hence this change
should be reverted in 4.8 when more efficient way of getting the id's
comes available.

Also used 'int' instead of QDeclarativeDebugObjectReference for
the debug id in order not to use the private API from QMLJS

When the document is reloaded by the server, we need to refresh
refresh what was the loaded document, and refresh the debugIds
