SBUMessageCellThemes not works correctly after v2.1.0
For Eaxmple, When I define custom image into SBU.iconDoneAll,
SBUMessageCellTheme.readReceiptStateColor and
SBUMessageCellTheme.deliveryReceiptStateColor don’t change colors properly.
Maybe, some confusing logic occurs after under replacement.
iconDelivered → iconDoneAll
iconRead → iconDoneAll
