Issue Description

I load gif with AnimatedImageView and set repeatCount .finite(count: 1) or .once, it plays two times!

Xcode11.1 + iOS 13.1.3

What

If i set repeatCount repeatCount .finite(count: 0), it did not play;
If i set repeatCount repeatCount .finite(count: 1) or .once, it played two times;
If i set repeatCount repeatCount .finite(count: 2), it played three times;

Reproduce

override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        self.imageView.repeatCount = .finite(count: 1)
        self.imageView.kf.setImage(
            with: LocalFileImageDataProvider(fileURL: xxxx),
            options: [.forceRefresh]
        )
    }

I can confirm this behaviour for the repeatCount property.
As a workaround i used the AnimatedImageViewDelegate method
animatedImageView(_:didPlayAnimationLoops:)
and the first time the method fires i did what i needed to do after the first end of the gif.

but using AnimatedImageViewDelegate doesn't give desired result because it stops the animation on first frame instead of last frame.

In my case the animation stopped after the last frame. I was using version 6.3.0 if it matters.
