Update initialize-account to latest ExampleNFT

based on the latest/greatest https://github.com/onflow/flow-nft/blob/master/contracts/ExampleNFT.cdc

I get the following error based on testnet.env config value NFTContractName=UFC_FIGHTER_NFT

thrown: "execution error code 1101: [Error Code: 1101] cadence runtime error Execution failed:
