Removing the reload (and the whole `componentDidMount` function since
the reload was the only thing in there) makes sure that the container
view isn't reloaded when the DOM changes and so does not make a request
to the container. Because of this change kitematic will not make a
request to the container when hovering over the preference button.
(I wasn't sure if this was used somewhere for real. If it is, I couldn't
find it).
Fixes#333.
