compositor: fix repaint on first wakeup

wlsc_compositor_fade() ends up in wlsc_compositor_schedule_repaint(),
which is a no-op if compositor is SLEEPING.

On wakeup, first set status to ACTIVE, then call wlsc_compositor_fade()
to start and actually show the animation.

Before, fade was called first, which reset the animation, but did not
cause a repaint. The following wakeup (any input event) would then cause
a repaint, showing the animation from the middle or end of it.
