fix(animation): Move cancel call to Animation struct

Only focused window was cancelling its animation because we call cancel
in window::set_position and waiting for its cancelling. And because we
waiting for cancelling second window is still moving. Second window will stop
moving only after the first window. So I moved `cancel` call to
Animation struct so its happening in its own thread and doesn't block
others animation moves and cancels.
