Test .kra file that causes a crash

Attempting to normally open the attached .kra file results in Krita master crashing with a segmentation fault - the file opens fine in 4.2.1 (distro package). It only contains a fill layer, a reference image and a few assistants.

Strangely enough the canvas acceleration sometimes gets disabled automatically, but the crash happens regardless of it being on or off.

Simply open the attached file in Krita and it should freeze or close completely.

Reference images seem to be the culprit, when all are removed it loads fine. Afterwards I can readd a reference image to the document, but when I close it and try to open again the same crash occurs.

Same result also with the Next appimage from yesterday.

Fix segfault when loading .kra file with a ref pic

There was a crash caused by not checking if anything is on the reference
images layer before updating it. This commit fixes this behaviour.
Reference images should still load just fine.
