Update requested state after applying pending frames 

When there is an insets animation, we will stop updating insets source
frames until the animation is done. The previous logic didn't update the
frames within the requested state while the animation is done. And the
frames was relied by InsetsPolicy while playing transient bar animation.
If the frames don't match the display, the insets would be wrong, and
the animation wouldn't be played correctly.

Test: atest InsetsControllerTest
