Remove redundancy of calling create_search_table() from outside the class.

When creating a SearchBar we've always called both create_search_table()
and create_complete_search_table(). The former produces all of the
'Table' elements and the latter produces all of the 'Operation' elements
by table.

This change removes some un-necessary redundancy.
