* Remove dropdown behaviour when switcher legitimately only contains a single locale

Addresses #7999. get_url_parts _should_ always return a valid result since we only run it on sites that the page belongs to, but if it doesn't, we don't want it to error out (since this is only a background task).
Fixes #8291. When results listings are generated as partial AJAX responses through the listing_results review, the 'next' parameter on those results should point back to the main 'index' view so that on return from the edit view, the user gets back a full page rather than a partial response.
