Follow up of #172 and #177

Calling allowance calls within Desktop Metamask fails, which would be fixed by MetaMask/metamask-extension#23527.

However, that wouldn't solve the problem of sending ETH to a contract address using eth_sendTransaction.

Sending ETH to a contract address always reverts when attribution option is true or undefined.

@dalechyn suggested we should have attribution flag false by default, and let users include them if needed.

Below is an example Warpcast Simulation parameters when sending ETH to a contract address using c.res or c.send.

transaction": {
    "method": "eth_sendTransaction",
    "params": {
        "to": "0xeac856237a85b70338a32b55bf44b13ef1a7811d",
        "data": "0xfc000023c0",
        "value": "5000000000000000",
        "chainId": "8453",
        "from": "0x130946d8dF113e45f44e13575012D0cFF1E53e37"
    }
},
