owncloud/ocis#7538

Needs owncloud/ocis#7540

Example

1. Create Space "Test" as Admin (Admin has the permission ReadOnlyPublicLinkPassword.Delete)
2. Invite Einstein as "Manager"
3. Create Folder "New folder"
4. As Einstein, create public link with "View" permission

No permission (Einstein)

As Einstein, try to remove the password after the link creation
