This is the same as gh-2442 but rebased onto develop.

Fix https://trac.openmicroscopy.org.uk/ome/ticket/12253

to test:
* Select an orphaned dataset is selected in Insight
* the toolbar gives the Copy option and Cut is greyed out
* the right-click menu gives the Edit > Cut option but the copy option is greyed out
