Don't show red dot for non-owned P/D/I S/P/A in tree. #11039

See ticket http://trac.openmicroscopy.org.uk/ome/ticket/11039
We now show the same icon for owned and non-owned objects in the Tree (don't use red dot for other users' data).

To test, browse other user's data or "All Members" and check that all icons are the same (no red dots).
