Properly fade recipient bar of incoming messages.

Browse Source 
This fixes #1682, a recent regression that came out of
a5a47e13fc9d, which introduced the update_rendered_messages()
function in compose_fade.js.  The original implementation
was finding the table row for a message, but not the table
row for its recipient bar.  Now we style both elements.
