Prevent EAD create event duplication. refs #7443

There were two places that EAD create events would get exported to,
causing duplication during roundtripping. Removed one of them.
Add option to export EAD like public user in CLI

If the '--public' option is added when executing the exportBulk task
draft descriptions (and their descendants) are not added in EAD export.
It won't add physloc either if physical storage is hidden for public user
