"Viewed by" shows the same thumbnail

[jburel]

"Viewed by" shows the same thumbnail for each user, regardless of real rendering settings

Context rwrw:

• user1, owner of the image (not owner of the group), changes settings,
• user2 can view settings set by user1 and the default view.
• user2 changes settings.
• user1 tries to view the thumbnail

  omero.SecurityViolation
      serverStackTrace = "ome.conditions.SecurityViolation: Updating ome.model.display.Thumbnail:Id_604 not allowed.

we use the method getThumbnail(sizeX, sizeY);

other scenario in rwrw--

• user1 imports image and changes Rendering to R1
• user2 looks at the image and changes settings to R2
• user3 owner of the group looks using "viewed by" and thumbail for user1 and user2 are the same
