Adds 4byte registry fallback to getMethodData() (#6435)

* Get contract method data from 4byte if we can't get it from eth-method-registry

* Clarify token method name fallback code in getMethodData

* Bugfix: don't attempt to translate falsy actionKeys in confirm-transaction-base.component.js

* Rewrite getMethodFrom4Byte with async-await

* Call four byte and method-registry requests in parallel in getMethodData()
