the join on id now fails, it does not deliver recently created disks
the problem is that disks that were created a few months or years ago only have am "id" after properties.osDisk.managedDisk. and the join relies on only receiving "id".
However, recently created disk also have a properties.osDisk.managedDisk.storageAccountType attribute which makes the join fail - the disks do not show up in the result.
