// ADD: CR #1894. Cascading deletes were throwing an unhandled exception because of a DB Foreign
// Key Constraint on the folderId field. What that means is that the ORDER in which things are
// deleted, now becomes very important. If we attempt to remove a 'container' before we remove
// the contents, the exception will be thrown when the contents are removed. So - in order to make
// this work, we group the objects to be deleted - and then we have to order those groups (since the
// order of the GroupBy could be non-deterministic) and make sure that we delete things in the
// correct sequence. There is probably a more elegant way of doing this - but there was no time.
