python: fix return value of emptiness_check_instantiator

Browse source 
* wrap/python/spot.i: Fix typemap for
emptiness_check_instantiator::construct.  The previous code used
to turn (None, "error") into simply ("error").
* wrap/python/ajax/spot.in: Fix handling or errors when
instantiating emptiness checks.
