Bug 509708 - Don't try to create an image from a null descriptor.

Elements in the outline can be "virtual" without real direction of the
change (e.g. "Compilation Unit" root node). Such elements are created
from RangeDifferences with "NOCHANGE" kind (so the
DocumentMerger.Diff.fDirection is zero), and therefore they do not have
an image descriptor configured in CompareConfiguration.fgImages array.
