Fixes VHO case from #69788.

On GetProperties of DerivedClass type object we want to return correctly inherited members. NewSlot values for sample hierarchy of entities are as follows:

BaseBaseClass{
  virtual string VHO = "BB"; // True (should be visible)
}
BaseClass: BaseBaseClass{
  new virtual string VHO = "B"; // True (should be hidden)
}
DerivedClass: BaseClass{
  override string VHO = "D"; // False (should be visible)
}

This means that if we detect a change between parents in newSlot value from False to True, we should hide the member that has the True value.
Till this moment we were hiding all members that have newSlot = True which resulted in hiding both "B" and "BB" and was incorrect - "BB" should not be missing.
