This fixes the from_str serialization. I discovered this while trying to serialize and deserialize the response type for broadcast_tx_commit while making a mock tendermint server; the gas_wanted field and a few others were serialized as integers, but were decoded as a string, causing an error invalid type: integer 0, expected a string at line 1 column 98. Display formats the integer without quotes, but we wanted with quotes.

Before:

"{\"jsonrpc\":\"2.0\",\"id\":1,\"result\":{\"check_tx\":{\"code\":0,\"data\":[],\"log\":\"\",\"info\":\"\",\"gas_wanted\":0,\"gas_used\":0,\"events\":[],\"codespace\":\"\",\"sender\":\"\",\"priority\":0,\"mempool_error\":\"\"},\"deliver_tx\":{\"code\":0,\"data\":[],\"log\":\"\",\"info\":\"\",\"gas_wanted\":0,\"gas_used\":0,\"events\":[],\"codespace\":\"\"},\"hash\":\"\",\"height\":\"1\"},\"error\":null}"

After:

"{\"jsonrpc\":\"2.0\",\"id\":1,\"result\":{\"check_tx\":{\"code\":0,\"data\":null,\"log\":\"\",\"info\":\"\",\"gas_wanted\":\"0\",\"gas_used\":\"0\",\"events\":[],\"codespace\":\"\",\"sender\":\"\",\"priority\":\"0\",\"mempool_error\":\"\"},\"deliver_tx\":{\"code\":0,\"data\":null,\"log\":\"\",\"info\":\"\",\"gas_wanted\":\"0\",\"gas_used\":\"0\",\"events\":[],\"codespace\":\"\"},\"hash\":\"0000000000000000000000000000000000000000000000000000000000000000\",\"height\":\"1\"},\"error\":null}"

Also made rpc::Wrapper::new_with_id public because I'm using it externally.
