The previous code is not incorrect since the method `SetBlockBloom` use the `ctx` passed in rather than the `k.ctx`.
It's confusing that sometimes methods use ctx in parameter, sometimes use `k.ctx`, but that's another issue.

- Adds ethermint query command (`emintcli query ethermint <query>`)
- Supports block number, storage, code, balance lookups
- Implements RPC API methods `eth_blockNumber`, `eth_getStorageAt`, `eth_getBalance`, and `eth_getCode`
- Adds tester utility for RPC calls
- Adheres to go test format, but should not be run with regular suite
- Requires daemon and RPC server to be running
- Excluded from `make test`, available with `make test-rpc`
