[BUGFIX] Check if '_ORIG_uid' really exists in ElementInformationCont…

…roller

The computed property '_ORIG_uid' is only set for workspace records,
which are NOT moved (t3ver_state=4). It is better to check directly for
the existence of this key as done in all other occurrences where it is
retrieved. The presence already ensures that we are dealing with an
overlaid workspace record and that there is need to fetch the original
uid.
