When using a non-translatable content object attribute with urls, creating a new translation will result in stale/invalid site link.

Steps to reproduce

1. Setup a content class with a non-translatable ezurl attribute
2. Create a content object, in language eng with url http://testurl.v1.en
3. Create and publish new translation of the object in any other language (Version 2) - the ezurl attribute cannot be modified.
4. Publish an additional version (3), in english once more, changing the url to http://testurl.v3.en

Result:

Both urls will be used by the linkcheck.php cronjob

Expected result:

According to the latest published version of the object, for any language, the (only) correct url should be http://testurl.v3.en
