load kwarg traits before loading config...
load kwarg traits before loading config in `Configurable.__init__` avoids problems in the new init of traitlets that skips `_trait_default` if specified in kwargs, which means really nothing should be done before `HasTraits.__init__` has been called. This does mean that such values are assigned twice. Typically, this will have no effect, except when a value is set by both config and kwarg.
