broken tests for using each_with_hit and search result order

[dwkoogt]

broken tests for using each_with_hit when the returned records should not be the natural order.

this is for issue #99

searching for 'code' returns 'Coding' first and 'Test Coding' second from elasticsearch.
it compares ids of db records to response result.

note: calling to_a within the each_with_hit method changes the _id behavior on the mongoid record. it returned string id originally but after to_a is called, it returns ObjectId instead.

@dwkoogt I've run bundle exec ruby -I lib:test test/integration/active_record_basic_test.rb on your branch now, and not getting any errors -- what kind of error do you get?

[dwkoogt]

active_record_basic_test.rb is a passing test just to illustrate the problem with mongoid. You need to run mongoid_basic_test.rb

[karmi]

So the problem is solely with the Mongoid adapter?

[karmi]

Right, so I can replicate the problem with Mongoid, the fix seems to be in calling to_a in the each_with and map_with methods.

Can you please sign the Contributor License Agreement so I can merge your test in?

We should name this better, something like should "preserve the search results order for records" do
