rpc: debug_traceTransaction fails for succesful tx (#720)

* Problem: traceTransaction fails for succesful tx

Solution:
- Change the context to the begining of the block, rather than the end
  of it, while override block context to correct one

pass predecessors

pass current block information to grpc query

* changelog

* fix build

* fix lint

* refactor traceBlock

* update protobuf

* fix Predecessors

* traceBlock refactor

* refactor traceBlock response

* Update proto/ethermint/evm/v1/tx.proto
