As per issue #1208 (closed) this PR updates the comments explaining that after ejecting and trying to add new loaders, the user must also add add the extension that loader is handling to the exclude list for the url loader.
I have made the original comment stand out more, and given a more practical example and have added a new comment to the edit of the loaders array where a person would usually add a new loader to warn them to update the exclude list.
Happy to hear feedback if this is over the top / not obvious enough.
