message_edit: Fix rendering bug when topic-editing single messages. 

If you topic-edited a single message within a narrow, we would update
all our unreads/sidebar/etc. data structures, and would rerender the
message if appropriate.  However, for the corner case of being inside
a topic narrow when you did this, we didn't have logic to remove the
message from the narrow (which is the appropriate situation when you
just topic-edited a message in a narrow).

When topic-editing multiple messages including the currently selected
message (the more common case), we would end up changing the narrow,
resulting in this issue being masked.

Fixes #11601.
