unit test for usdc/usdt bug

[mzywang]

this function https://github.com/Uniswap/v3-subgraph/blob/1394f592aa84970ab5c4e30e2f7d0b5a02c57b89/src/utils/pricing.ts#L139 seems to be improperly setting the amountUSD on some transactions

e.g.

query swaps {
  token0: token(
    id: "0xaf88d065e77c8cc2239327c5edb3a432268e5831"
    block: {number: 242204912}
  ) {
    derivedETH
    decimals
    name
    id
    symbol
  }
  token1: token(
    id: "0xfd086bc7cd5c481dcc9c85ebe478a1c0b69fcbb9"
    block: {number: 242204912}
  ) {
    derivedETH
    decimals
    name
    id
    symbol
  }
  bundle(id: 1, block: {number: 242204912}) {
    ethPriceUSD
  }
  txbad: transaction(
    id: "0x67af911966300410dad78d13e267fdf2087324936d1908ba3f33342af6e299c1"
  ) {
    blockNumber
    swaps {
      pool {
        id
      }
      id
      amount0
      amount1
      amountUSD
      timestamp
      token0 {
        id
      }
      token1 {
        id
      }
    }
  }
  txgood: transaction(
    id: "0x5a6e6b99ee6301f11d5364607eb804e4268017c9ffc24f9841433fd6f78ef79f"
  ) {
    blockNumber
    swaps {
      pool {
        id
      }
      id
      amount0
      amount1
      amountUSD
      timestamp
      token0 {
        id
      }
      token1 {
        id
      }
    }
  }
}

returns

}

for the bad transaction, it seems like it's taking token0's price and for the good transaction it seems to be taking token1's price even though it should only be taking token1's price based on configured list of whitelistedTokens
