Fix ignore_unmapped setting when using geo_shape query with a pre-indexed shape (elastic#136961) (elastic#136975)

GeoShapeQueryBuilder ignores the value of ignoreUnmapped when rewriting the query so those queries always
get a false value. This commit make sure the variable gets correctly assigned.
