Fix regression in bubble animation

This was a bug introduced in ag/28230638. Accidentally passed the
wrong boolean value. The bug is that the initial state animation
does not play, and the bubble bar remains invisible.

Flag: com.android.wm.shell.enable_bubble_bar
Fixes: 352119655
Fixes: 352412093
Test: manual
       - Clear all bubbles
       - Send initial bubble
       - Observe that the initial state animation plays correctly
