Improve error presentation to user.

[MicahZoltu]

user rejected action (action="sendTransaction", reason="rejected", info={ "error": { "code": 4001, "data": { "request": { "method": "eth_sendTransaction", "params": [ { "data": "0xa9059cbb000000000000000000000000d8da6bf26964af9d7eed9e03e53415d37aa9604500000000000000000000000000000000000000000000000000000f478e084000", "from": "0xd8da6bf26964af9d7eed9e03e53415d37aa96045", "gas": "0x8ee2", "to": "0x1f9840a85d5af5bf1d1762f925bdaddc4201f984" } ] } }, "message": "ethers-user-denied: Interceptor Tx Signature: User denied transaction signature." }, "payload": { "id": 52, "jsonrpc": "2.0", "method": "eth_sendTransaction", "params": [ { "data": "0xa9059cbb000000000000000000000000d8da6bf26964af9d7eed9e03e53415d37aa9604500000000000000000000000000000000000000000000000000000f478e084000", "from": "0xd8da6bf26964af9d7eed9e03e53415d37aa96045", "gas": "0x8ee2", "to": "0x1f9840a85d5af5bf1d1762f925bdaddc4201f984" } ] } }, code=ACTION_REJECTED, version=6.6.1)

We should parse the error and look for and handle well known error codes. We should work with @KillariDev to ensure we at least support all of the Interceptor errors and present them to the user in a nice clean way.

We should still include the JSON, but perhaps hidden behind an Additional Details

section or something.

Note: this is relatively low priority.

• if error code is recognized, present nice human readable error to the user
• if error code is not recognized, present error.message clearly, and put error.data and any other details hidden behind a Details box or similar.
• ethers error call_exception -> parse inner error message only

errors in ethers

Closing with #210 having merged, which addresses this feature.
