Allow all islands for builtworks 2d representation

[RemoGrillo]

Currently the connection of autocomplete of 2d representations is only available for san secondo. ?root rs_sql_sail:hasQueryId "sansecondo_buildings"; We should test the general query instead of the table based one (no need to select that for performance issues)

The query is correct; the issue was in the database. See https://github.com/villaitatti/VeNiss_queries.
