Describe the bug

Lottie 4.2.1
this is rare crash - I had it once.

java.lang.NullPointerException: Attempt to read from field 'float android.graphics.PointF.x' on a null object reference
    at com.airbnb.lottie.animation.keyframe.TransformKeyframeAnimation.getMatrix(TransformKeyframeAnimation.java:172)
    at com.airbnb.lottie.model.layer.BaseLayer.getBounds(BaseLayer.java:217)
    at com.airbnb.lottie.model.layer.CompositionLayer.getBounds(CompositionLayer.java:128)
    at com.airbnb.lottie.model.layer.CompositionLayer.getBounds(CompositionLayer.java:131)

It looks like positionValue is null so additional null check is needed besides this added in #1917
