Small refactoring opportunity

[epugh]

At one point, echoParams=all was set by Quepid, but these days Splainer-search does it.

Remove lines 83 in QueriesSvc:

          // add echoParams=all if we don't have it defined to provide query details.
            if (args['echoParams'] === undefined) {
              args['echoParams'] = 'all';
            }

And make sure we get echoParams ;-)
