Component name is not preserved when wrapping

[ashbrowning]

When wrapping a component, the name of the component is not carried through to the wrapped component. This means that when snapshot testing or viewing stack traces, a wrapped component will always have the name of Component rather than the original (and less generic) name, which can hamper debugging.

To fix, the name of the component can be assigned to the displayName property of the returned Wrap component. Something similar is done in the isomorphic-style-loader
