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`
- Implemented AppModule interface and added EVM module to app
- Required for routing
- Implements `InitGenesis` (`x/evm/genesis.go`) and stubs `ExportGenesis`
- Modifies GenesisAccount to match expected format
- Implements Keeper. This is a wrapper around the "real" keeper (CSDB). Since we need to pass the context into the keeper we need to abstract the CSDB from the
- Adds WithContext() to CSDB to support the above requirement
- Adds Keeper to app
