!fix(evm): Fix eth tx hashes in json-rpc responses (#1176)
* Fix eth tx hashes in json-rpc responses

Closes: #1175

- Remove Size_ field
- Validate From/Hash fields in ante handler
- Recompute tx hashes in json-rpc apis to cope with old blocks

Update CHANGELOG.md

remove Size_, validate Hash/From, add unit tests

update spec

Update CHANGELOG.md

Update app/ante/eth.go

populate From in SendRawTransaction

Apply suggestions from code review

keep Size_ field to avoid breaking tx format

* move some validation to ValidateBasic

* move validation to ValidateBasic

* make ToTransaction returns a valid msg

* restructure the protoTxProvider check

* add comment

* workaround tx hash issue in event parsing

* fix integration test

* fix unit test
