OpenLayers preview do not report exceptions "in image" anymore

Description

Once upon a time we used to have them, while not everybody was able to parse them, we'd at least provide some info as to why a preview, or a filter in a preview, was failing. Right now there is nothing, one has to be admin and look in the logs.
