Fetch revert reason for sendSignedTransaction

[cgewecke]

Description

Adds revert reason support to sendSignedTransaction (eth_sendRawTransaction).

Fetches transaction object for the failed tx and synthesizes unsigned tx params for it so it can be replayed as an eth_call whose return data is parsed as a revert reason.

Fixes #3345

LGTM, and looks like travis reported the test successfully 👍 sendSignedTransaction reverts with reason (53ms)
