Fix preanims not playing on blank posts

The early return guard `textnow === chatmsg.content` was firing on the
first tick for empty messages ("" === ""), short-circuiting the entire
animation timeline before the preanim or shout phases could run.

Now the guard also checks that both tick phases have completed before
allowing the early exit.
