Retry the deposits automatically

[jonasraoni]

Some deposits, that might have failed due to local issues (harvest-error, xml-error, bag-error, ...) might be retried automatically after upgrading the application.

• Store the application version when creating the package
• If a deposit failed with a recoverable error, attempt to resubmit automatically once the application has been upgraded
• Existing deposits with a recoverable might skip the version check if the field is empty
