test: add failing test to demonstrate error using ref (#282)

Browse source 
Filtering on ref in this manner worked up until Ash 3.0. Now, it gives
the following error:

1) test filter with ref (AshPostgres.FilterTest)
     test/filter_test.exs:1076
     ** (FunctionClauseError) no function clause matching in Ash.Filter.check_filterable/2

     The following arguments were given to Ash.Filter.check_filterable/2:

         # 1
         AshPostgres.Test.Organization

         # 2
         :id

     Attempted function clauses (showing 2 out of 2):

         defp check_filterable(_resource, [])
         defp check_filterable(resource, [relationship | rest])

     code: |> Ash.Query.filter(^ref(:id, [:posts, :comments]) == ^comment.id)
