Leaked elixir is displayed incorrectly for duels

[ma-ruz]

In CR API, there is info about leaked elixir for each round of duel separately (in PlayerBattleRound.elixirLeaked). However, RoyaleAPI displays the leaked elixir from the battle total (in PlayerBattleData.elixirLeaked) which is just some pseudorandom value for duels. This wrong value is displayed below each round info and also at the end of the replay section.
