Symbol Editor: Moving any pin will move all edited earlier pins to one place

[Grzegorz Obuch]

1. Open/create any symbol.
2. Edit at least two pins, changing anything.
3. Select and move any pin - it can be different than edited.
4. When you place the moved pin in the new position, all edited pins jump to the same position.
5. Undo repair that.
6. Last edited pin is still highlighted, but _not selected_ for any operations,even after selecting any other pin.
