doc: Remove "current child" code

The current child concept was added to the Name
Collision Node to heuristically provide better
linking when a link operation reached a collision
node. It is doubtful that this improved linking
much, but now that qdoc uses multiple trees, it
is much less likely that collision nodes will
occur. In fact, there are none in in the current
Qt5. Therefore, the current child code is hereby
removed from qdoc.

Task-number: QTBUG-37067
