[ChaituVR]

Fixes #7

• Using the checksummed address to calculate delegation voting power

How to test

• Try this query

query ($first: Int!, $skip: Int!, $orderBy: Delegate_orderBy!, $orderDirection: OrderDirection!, $governance: String!) {
  delegates(
    first: $first
    skip: $skip
    orderBy: $orderBy
    orderDirection: $orderDirection
    where: {tokenHoldersRepresentedAmount_gte: 0, governance: $governance}
  ) {
    id
    user
    delegatedVotes
    delegatedVotesRaw
    tokenHoldersRepresentedAmount
  }
  governance(id: $governance) {
    delegatedVotes
    totalDelegates
  }
}

variable

{
  "orderBy": "delegatedVotes",
  "orderDirection": "desc",
  "skip": 0,
  "first": 40,
  "governance": "moxie.eth"
}

Before the fix, it will return empty delegations. and after fix it will return delegations
