[BUG] Incorrect token address for curve trades on metapool #8376
Description
Description
In curve metapool when the buy token(j) index is 0 the token sold is added to underlying liquidity pool and the token amount for sold token(i) reflected in the TokenExchangeUnderlying event is the amount of lp tokens that were minted when the sold token was added to liqudity pool instead of token sold amount of the actual underlying token.
Current behavior
`tokens_sold : 2308540548419464479212` is the number of lp token minted and not the actual amount of token sold. Actual token sold amount is `2316461131 USDC`

Expected behavior
The token_sold_address should be either the LP token, or token_sold_amount_raw should be the real amount of underlying tokens that were sold.
