* Keep the send button when the composer is emptied while editing
rememberEndButtonParams checked whether the composer had sendable text
before it checked whether the user was editing a message, so clearing
the text of a message being edited replaced the send button with the
voice recorder button. Starting a recording from there abandons the
edit.
Check the editing branch first, as the formatting composer already does,
and let it render a disabled send button when there is nothing to send.
