[Investigate] Historical account information incorrect before creation

[fabrice102]

Summary

When querying the account information for a round before the account creation, instead of indicating that the account does not exist, the indexer returns values that do not seem to match anything I could see.

For example:

curl -s "https://indexerURL/v2/accounts/IWG4ZPOKGVS554U4HBKQEHHAQTV5EH2A4A6QSYWLG66MSSMA523CK4DZ6A?round=1000000" | jq

returns

{
  "account": {
    "address": "IWG4ZPOKGVS554U4HBKQEHHAQTV5EH2A4A6QSYWLG66MSSMA523CK4DZ6A",
    "amount": 200000,
    "amount-without-pending-rewards": 200000,
    "pending-rewards": 0,
    "reward-base": 143051,
    "rewards": 0,
    "round": 1000000,
    "sig-type": "sig",
    "status": "Offline"
  },
  "current-round": 9481115
}

while the account was only created at round 8709370 and received 9.99 Algos (https://algoexplorer.io/tx/FIH3KER5D5GABDVOCZRSUCPNHNFUJ6IWNB6PIN5JCWHUD3HJR34A).
