Remove Restore Backup Action For Non-Completed

the "restore backup" action is incorrectly shown for an uncompleted
database backup in the database backups table. now, only if the
backup is completed, will the action/button appear.

in addition, uncompleted backups are now excluded from the dropdown
in the create-instance workflow.
