Summary:                    Type of operation->insert_templates depends on
Update syntax
Description: 
The code below works fine, but if you uncomment the prepare line, and comment
out the one above it segfaults.

It seems that if the operation includes a WHERE clause then you get rasqal graph
patterns in insert_templates, and if it doesn't you get rasqal triples.

It seems like it would be more convienient to always get rasqal triples, as only
GRAPH is allowed in the template slots anyway.

Steps to Reproduce: 
#include <raptor2/raptor.h>
#include <rasqal/rasqal.h>

int main()
{
    rasqal_world *rasworld = rasqal_new_world();
    raptor_world *rapworld = raptor_new_world();

    rasqal_query *q = rasqal_new_query(rasworld, "sparql11-update", NULL);
    raptor_uri *bu = raptor_new_uri(rapworld, (unsigned char *)"local:local");
    rasqal_query_prepare(q, (unsigned char *)"INSERT { <a> <b> <c> } WHERE { ?x
?y ?z }", bu);
    //rasqal_query_prepare(q, (unsigned char *)"INSERT DATA { <a> <b> <c> }",
bu);
    rasqal_update_operation *op = rasqal_query_get_update_operation(q, 0);
    rasqal_graph_pattern *gp = raptor_sequence_get_at(op->insert_templates, 0);
    rasqal_query_print(q, stdout);
    rasqal_graph_pattern_print(gp, stdout);

    return 0;
}
