REQ message fails because of timeout method resolution

The use of `timeout` resolving via `method_missing` in https://github.com/copiousfreetime/krakow/blob/master/lib/krakow/command/req.rb#L11 results in `timeout` from timeout.rb being called instead of the local accessor method.

This fixes this and a method spelling error and the resolution of the `LookupError` exception. All of which appear to be required to do requeueing.
