Only render Live editor save button when content type is set

This PR is a follow up on #6178. Instead of trying to render the save button on every page in the back-end, only try when we're actually editing content. Otherwise Bolt will break since no contenttype is set.

I'll have a dig for you.

Thanks @GawainLynch! I'm not too familiar with testing, so I guess I have some reading up to do.
