BUG: session reference count not copied on update — at Version 3

Reported by:	jamoore	Owned by:	jmoore
Priority:	blocker	Milestone:	OMERO-Beta4.2.1

Description (last modified by jmoore)

In several places (e.g. SessionManagerImpl update() and reload()), SessionContextImpl instances are recreated with the values from previous contexts without having the reference values copied leading to exceptions like the one below.

This issue was discovered via the many logging statements added as commits to #2804, which is partially but not completely related.

Previous description

During really long method calls (saveToDb) sessions are being closed by some combination of left over sessions. (#2772 and from OmeroCli).
