streams: Fix live update of stream name when renamed. 

Currently, the Stream Name change isn't reflected in the streams
sidebar when a stream is renamed if the order of streams in the
sidebar remains unchanged, because the optimization to avoid
rerendering when nothing changes about the order prevents the
rerendering code from running.

We fix by this adding a flag in build_stream_list and
update_streams_sidebar functions to force a rerender, and pass that
when a stream is renamed.

Fixes #16026.
