Summary:                    librdf error - query language vsparql already
registered
Description: 
When librdf is compiled as a static library with Modules turned off and Virtuoso
support turned on, I get the following error message while librdf is starting
up:

librdf error - query language vsparql already registered

This seems to be caused by librdf_init_query_virtuoso() being called twice. 

The first call is in the Virtuoso storage initialisation:
https://github.com/dajobe/librdf/blob/master/src/rdf_storage_virtuoso.c#L3081
https://github.com/dajobe/librdf/blob/master/src/rdf_storage_virtuoso.c#L3098

The other call is in librdf_init_query():
https://github.com/dajobe/librdf/blob/master/src/rdf_query.c#L75
(this is only called if modules are enabled).


Would it be wrong to remove the call to librdf_init_query_virtuoso() in
rdf_query.c?
I am not sure why there is there?
