Fixed bug 34119: Sync terminology doesn't translate some PO window fields.

In Synchronize Terminology the PO field's name is taken from its element instead of the element's translation (when available) when the element's PO_NAME field is empty.
Now the element's translation takes precedence over the element values. It is ordered as follows:

ad_element_trl.PO_NAME > ad_element.po_name > ad_element_trl.name > ad_element.name
