bug with collectedFeesTokenx always equal to zero

[macmiller]

In the hosted subgraph: https://api.thegraph.com/subgraphs/name/uniswap/uniswap-v3 running a query on positions the collectedFeesToken0 and 1 always returns zero. 1.) Run this query:

{
  positions(first: 100, where: {id_gt: "410000"}) {
    depositedToken0
	depositedToken1
	withdrawnToken0
	withdrawnToken1
    collectedFeesToken0
	collectedFeesToken1

  }
}

Note the collectedFees always is equal to zero. 2.) Run this query:

{
positions(first: 20, orderBy: id, orderDirection: desc, where: {collectedFeesToken0_gt: 0}){
	id
	collectedFeesToken0
}
}

Note the collectedFees on nft position IDs up to 5 digits (max 99999) was normal. Sometimes they are zero (when they should be) but often times the collectedFess returns an actual value accurately. Also, running the first query against the revert finance version shows they have found and fixed the issue and it works as expected. https://api.thegraph.com/subgraphs/name/revert-finance/uniswap-v3-mainnet
