order causing CI failure

[loay]

It looks like the CI is failing due to order is not set in the db, causing the following:

 1) basic-querying find supports non-empty inq:

      AssertionError: expected Array [ 1, 0 ] to equal Array [ 0, 1 ] (at '0', A has 1 and B has 0)
      + expected - actual

       [
      +  0
         1
      -  0
       ]

We can maybe use a similar solution like:

var idName = this.idName(model);
If (!order) {
order = idName;
}
