Remove tab display name experiment (not working)

- Tab display names should hold display name but...
 - Server sends <UUID, name, null> x Player count
 - TabListPlus sends <SlotID, ???tab#01, SlotText> x Slot Count
 - So we don't have player display names, only worthless slots
 - So the whole feature was useless, reverting to name only.
