opaque ids spec not implemented correctly

[mihaidma]

A string as the first parm position is an opaque id:
senecajs/seneca-store-test#16 (comment)

The query builder implements something like (https://github.com/senecajs/seneca-standard-query/blob/master/lib/query-builder.js#L378):

function buildSelectStatementCustom (qent, q, sTypes, selectstm, selectstmOr, done) {
    var query

    if (_.isString(q)) {
      return done(null, q)
    }

This needs to be deprecated in the favor of native$.
String in this position should be an opaque id

The test case: https://github.com/senecajs/seneca-store-test/blob/master/store-test.js#L557
