Fix HasMenuCurrent and IsDescendant/IsAncestor when comparing to itself

Browse source 
There may be sites in the wild that depends on the faulty behaviour of IsDescendant/IsAncestor when comparing to itself, but

* The documentation and common sense says that a thing cannot be descendant or ancestor to itself.
* The bug introduced in `HasMenuCurrent` comes directly from that confusion.

Fixes #9846
