message_feed_ui: Remove previous date from date separators. 

This commit updates the date row between messages and message
groups, removing the date of the previous message along with
the down arrow for the next message.

The goal of this commit is to declutter the message feed UI
as part of the redesign.

The change concerns the render functions in
timerender.js along with the files that reference these.

Fixes: #22967.
