Updating ethereum version from fork (#68)

* syncing with updated ethereum version with local versions

* Revert updates back to go-ethereum v1.8.27

* Fixed chain-test change from undoing recent go-ethereum changes

* Fixes linting issues

* Remove unused interface implementations

* Updates cosmos-sdk version from relative dependency and updates auxiliary changes

* Upgrading ethereum version back to most recent since 1.9 release <:)
