Exception when setting null drawable

[markusressel]

Describe the bug

Setting a null drawable strangely causes the Drawables without intrinsic dimensions (such as a solid color) are not supported exception to trigger. It seems like passing a null value to the setImageDrawable function actually results in setting a BitmapDrawable, see screenshot below.

• Library version: 1.8.0
• Reproducible in official demo app: no
• Device / Android version: OnePlus 6T API 29

To Reproduce

Steps to reproduce the behavior, possibly in the demo app:

1. Open something using ZoomImageView
2. use zoomImageView.setImageBitmap(null)
3. See error

Expected behavior

Not sure, but I guess it should be possible to set a null image (simply show nothing at all).
