Improve error message on Move data

[pwalczysko]

The error message such as 'cannot move channel[xxxxx] while LogicalChannel[xxxxx] remains when a Move of derived images is attempted, such as Projections, and the original image is left in original group is insufficient.

As reported recently by @mporter-gre, the follow-up hql query
omero hql -q --limit=10 --all "select id, pixels from Channel where logicalChannel=9428714"
followed by
omero hql -q --limit=10 --all "select p.image from Pixels p where p.id=4319640"

is simply too much even for a user who is familiar with OMERO concepts.
The question is whether we could not offer the Image IDs in the error message instead ?

Further, @mporter-gre suggested

A detailed description of the projects and datasets would be nice, like when you click the 'Show parent projects/datasets' button in web.
