Resource Type without date fields breaks Policy Sets import

[fyrbach]

The Policy Sets import in XUI ends with 500 Internal Server Error when there is a Resource Type without creationDate or lastModifiedDate LDAP attribute.

Such Resource Type can be created using ssoadm create-sub-cfg command and properties file with missing any of the mentioned attributes.

The import fails on following lines:
