efl_canvas_animation_player: fix to apply animation when player starts 

Previously, animation was not applied immediately when player starts
animation because elapsed time is 0.
This caused flickering object if animation begins with alpha 0 because
the alpha 0 animation is not applied immediately.

Now, animation is applied immediately when player start animation.
