Return invalid variant instead of null variant when feature has no ge…


Otherwise the sip wrapper around the returned variant does NOT
return true to QVariant::isNull() when run from outside QgsApplication.

Anyway, it's more sane and brings this function into line with
the other expression functions which return QVariants() instead
of usertype null QVariants
