typing: Fix assertion error when narrowed to a non existing stream.

Browse Source 
When narrowing to a stream which doesn't exist, the
code to render users who are typing in that narrow
resulted in an assertion error as the stream didn't exist.

This commit removes the assertion and returns an empty array
(array of users who are typing) in such case to fix the issue.
