e4e1b62 broke `to_param` handling:
- There was an issue inside controller tests where order params were not respected, the reason
was because we were calling `Hash#to_query` which sorts the results lexicographically.
1e4e1b62 fixed that issue by not using `to_query` but instead a utility function provided by rack.
- However with the fix came another issue where it's now no longer possible to do this
```
post :foo, params: { user: User.first }
# Prior to the patch the controller will receive { "user" => "1" }
# Whereas now you get { "user": "#<User: ...>" }
```
The fix in this PR is to modify `Hash#to_query` to sort only when it
doesn't contain an array structure that looks something like "bar[]"
