Fix divider bar not shown when entering split with rotation transition

When launching tasks into split with rotation transition, launch won't
handle divider bar fade-in animation because wm-shell will re-render a
new divider bar to apply new rotation config. This makes sure to clear
the divider bar remote animating flag before re-rendering the divider
bar for rotation so wm-shell can finish showing divider bar after
re-rendered it.

Fix: 232043721
Test: enter split with rotation transition, verified divider bar shown.
