    Bug Fix Enumerator::Lazy#uniq state for multiple call

    * enumerator.c (lazy_uniq_i): create new hash for each calls.
      [Fix GH-1820]

    Currently

            2.5.0-preview1 :001 > arr = (0..100).lazy.uniq{|i| i % 10}
             => #<Enumerator::Lazy: #<Enumerator::Lazy: 0..100>:uniq>
            2.5.0-preview1 :002 > arr.to_a
             => [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
            2.5.0-preview1 :003 > arr.to_a
             => []

    Expected

    arr.to_a to always return same output

    * test/ruby/test_enumerator.rb (test_uniq): remove assertions
      which ared duplicate of lazy enumerator tests in
      test_lazy_enumerator.rb.
