Bug

What is the current behavior?

Which are the steps to reproduce?

What is the expected or desired behavior?

The org info tab has an image field for the logo.
If that image is empty, then we get a NPE.

trace: ["java.lang.NullPointerException",…]
0: "java.lang.NullPointerException"
1: "\tat java.io.ByteArrayInputStream.<init>(ByteArrayInputStream.java:106)"
2: "\tat org.compiere.model.MImage.getScaledImageData(MImage.java:389)"
3: "\tat de.metas.ui.web.upload.WebuiImage.getImageData(WebuiImage.java:82)"
4: "\tat de.metas.ui.web.upload.WebuiImage.toResponseEntity(WebuiImage.java:110)"
5: "\tat de.metas.ui.web.upload.ImageRestController.lambda$getImage$1(ImageRestController.java:85)"
6: "\tat de.metas.ui.web.cache.ETagResponseEntityBuilder.toResponseEntity(ETagResponseEntityBuilder.java:230)"
7: "\tat de.metas.ui.web.upload.ImageRestController.getImage(ImageRestController.java:85)"
8: "\tat sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)"

But basically, any window that has a field which is image is not working anymore.
