Columns order in select clause is not kept in Ruby hash.

[sl-victorceron]

There is a different behaviour of our fork of snowplow-dashboard since update to Rails 4.2.x and rorschart 0.20.0

Before :

After update to Rails 4.2.x
.

In this example the date column was the first one in the select clause.
In the returned Ruby hash from the ActiveRecord object the date column is the second and country (in this example) is now the first column.

So, the order from attributs method in this line is different; it seems it comes from this Rails update.
