Contracts with the same name in an account?

[LanfordCai]

Current Behavior

account.contracts.names may returns duplicate contract names

Expected Behavior

account.contracts.names returns unique contract names

Steps To Reproduce

script:

  pub fun main(address: Address): [String] {
    let account = getAccount(address)
    return account.contracts.names
  }

command:
flow scripts execute ./scripts/get_contracts.cdc 0xf233dcee88fe0abe --network=mainnet

result:
["FungibleToken", "FungibleToken", "FungibleTokenMetadataViews", "FungibleTokenSwitchboard"]

There are two "FungibleToken"

Environment

- Cadence version: v0.31.0
- Network: Mainnet

@LanfordCai Thanks for reporting this inconsistency!

Notes:

Cadence gets the contract names of an account by calling into FVM through the runtime.Interface.GetAccountContractNames function. It seems like FVM returns duplicates.
