FIX: allow slug-less topic URLs to work within the same topic (#15508)
- Update the TOPIC_URL_REGEXP in `lib/url` so that `navigatedToPost` doesn't attempt to handle slug-less URLs. Slugs must contain at least one non-numeric character, so we can use that fact to make the regex more specific. We want slug-less URLs to be routed as a normal Ember transition, so that `topic-by-slug-or-id` can catch them and re-write the URL to include the slug.

- Update the `topic-by-slug-or-id` afterModel to ensure that the Ember router is used to handle the redirect, rather than DiscourseURL. This guarantees that it will function as a redirect (DiscourseURL.routeTo sometimes bypasses the router). This solves the history problem which was worked-around in 27211ee7bbf661991cbf8a69f98d490be233ae26.

- Update routes/topic to recover from aborted transitions gracefully. This means that following an aborted transition, the browser URL continues to be updated with post numbers as the user scrolls down the page.
