Have you looked arond at your directories on disk? I'm _not_ talking about the admin UI here. The default is "core discovery" mode, which recursively looks under solr_home and thinks there's a core wherever it finds a "core.properties" file. If you find such a thing, rename it or remove the directory.
Another alternative would be to push a configset named "new_core" up to Zookeeper, that might allow you to see (and then delete) the collection new_core belongs to. It looks like you tried to use the admin UI to create a core and it's all local or something like that.
