[gnome-db] no results != error

[Murray Cumming <murrayc murrayc com>]

It looks like gda_connection_execute_single_command() returns a NULL
GdaDataModel when the SQL query returns no rows. It also returns a NULL
GdaDataModel when there was an error with the SQL query. I don't think
they are the same thing. Can't it just return a GdaDataModel with zero
rows (and maybe some columns)?
