Specify when an EVM transaction has failed

[LefterisJP]

Abstract

At the moment there is no way to see that a history even of gas burning is due to a failed transaction.

As an example check this https://etherscan.io/tx/0xfbfd35db096d0acb26a988895841d786baafe08f6cf55265338e0b5db58350ee transaction.

In rotki it appears like this

It just shows the burned gas from the failed transaction but nothing else. It looks like a not properly decoded event and not a failed transaction. It would be good to somehow specify it and show in the UI.

Task

• Figure out the best way to show it it in the backend. Perhaps specific type/subtype + CPT_GAS?
• Figoure out how to best represent in the frontend. Specific event type showing a failed icon would make sense.
