Move to uploadedDIPs fails when DIP already exists
|Google Code Legacy ID:||Pull Request:|
Noticed by users testing AIP re-ingest. When you have already created a DIP from a SIP and uploaded or stored, a copy of the DIP is moved to uploadedDIPs. If you then create another DIP by re-ingesting the AIP, the Move to uploadedDIPs micro-service fails because there is already a DIP with the same name in that directory.
A work around is to clean out the uploadedDIPs directory before re-ingesting the AIP for new DIP creation.
