Revert PR#47 "Add #to_ary to Diff::LCS::Change…"

This reverts commits 01e0cae and 3b4d2be because they introduce fatally
breaking changes in the tests that were hidden by broken CI.

* 01e0cae: Add #to_ary to Diff::LCS::Change and Diff::LCS::ContextChange
  [Akinori MUSHA]
* 3b4d2be: Mention in rdoc that Diff::LCS::ContextChange can be converted to an
  array [Akinori MUSHA]
