FIX: Abort transition when transition.from present on new-topic route (#22253)
Why is this change required?

The `/new-topic` route is a special route which we use to open the
composer by loading a URL. By default, the `new-topic` route is replaced with the
`discovery.latest` route. On a fresh page load, this makes sense since
there is no template for the `new-topic` route to render. However, this
behavior does not make sense if we're transition from another route.
There is no need to replace the current route with the `discovery.latest` when all we want
is to open the composer.

What does this commit do?

This commit fixes the undesirable behaviour described above by aborting
the existing transition to the `new-topic` route if `transition.from` is
present. This indicates that we're navigating from an existing route and
we can just open the composer.
