In Conpherence, stop throwing away stuff users have typed when a reply arrives

Summary:
Ref T12562. I think the pre-send-on-enter behavior was: disable textarea, send message, clear area on response?

That got changed but not completely, maybe. There's currently an issue here:

  - Add a `sleep(3)` to `UpdateController`.
  - Type "AAA".
  - Press enter.
  - Real fast, type "BBB".
  - When the "AAA" arrives, your "BBB" is lost. Sad!

Test Plan:
  - Did the thing described above; no longer lost "BBB".
  - Switched threads, sent messages, couldn't find anything else this breaks. It dates from a long time ago so I think it's just pre-SOE stuff.
