[web][bug] incorrect aspect ratio and missing image "explorer" window in preview tab

For a public user without rendering settings for an image, the preview pane aspect ratio is incorrect and the navigation thumbnail window is missing.

Steps to reproduce:

• create public user group
• add an admin and a non-admin user to the public group
• with the admin user import an image with an odd aspect ratio, choosing to skip thumbnail generation
• using OMERO.web, login as public user and view the imported image in the preview pane
• note the aspect ratio of the preview image under user settings

Interestingly, I don't see the same issue if I import the image normally (without --skip thumbnails).

If I import 1 image with --skip thumbnails and 1 normally, then delete rendering defs on both images with omero delete Image/RenderingDef:79953. Then view them as public user as above, this forces the public user to create rdef and thumbnail, but ONLY the thumbnail for image imported with --skip thumbnails shows the problem above.

Also, if I delete RenderingDefs, then the Owner of the image is the first to view it (and create thumbs etc), now I can no-longer create the wrong-sized thumbnail for public user, even by deleting the RenderingDefs again and viewing the image first as public user as I did above.
