So it.next() will be false, and the function will loop. If the error persists, it will loop forever.
The query can give an error - I wrote the patch because it happened to me.
For some reason which I tried to debug but am now unable to reproduce at all,
during a query slightly prior to this function, the socket connection to virtuoso was lost.
But *just in case* it happens again, best not to loop.</pre>

query in createUri (for example, the connection to the
server died). Instead just return an empty url.
Also check for such an error with createGraph in ResourceMerger::merge.
This fixes a bug sort of introduced by b54cbaa5e00c1191cd2e66399aeb86a04ba85ef1.
If something went wrong with virtuoso, xsession-errors would fill up the
available space, because each loop called executeQuery and added an error message to the log.
