TT#26652 fix subscriberregistration API internal rs query

* search_rs(undef... did not work as the related query
      contained a non-existing column 'aor', failing it silentlly
      and caused a full join select without the where clause
    * search() now provides with a fail immediately if a column does not
      exist
