Return orders as an array instead of a string

[jdurand]

Joining the order clauses caused non-string clauses (Arel nodes) to be appended as a string :

Model.order(featured: :desc).order_by_rand(seed: session[:order_seed])
=>
[...] ORDER BY #<Arel::Nodes::Descending:0x007fe60af66858>, (SUBSTR(businesses.id * 0.5488135039273248, LENGTH(businesses.id) + 2)) LIMIT 12 OFFSET 0

Thanks for contributing!

I haven't checked out this specific case yet because it appears that all the tests were failing in master branch due to some minitest changes. I fixed those today.

As a first step, please merge master into your branch and ensure the tests pass. In addition, if you could add a test to ensure the behavior you were seeing works :)

Sorry took so long on this! Thanks for the fix 👍
