add specs for Layout/RescueEnsureAlignment fix c8ab8d9 from #6254

[oehlschl]

This PR demonstrates that there are still unexpected issues with Layout/RescueEnsureAlignment even after issue #6254 was resolved. I'm not familiar enough with Rubocop internals to resolve the issue, but the specs still failing include the original test case from @ashmaroli.

• Commit message starts with [Fix #issue-number] (if the related issue exists).
• Feature branch is up-to-date with master (if not - rebase it).
• Squashed related commits together.
• Added tests.
• Added an entry to the Changelog if the new code introduces user-observable changes. See changelog entry format.
• The PR relates to only one subject with a clear title
  and description in grammatically correct, complete sentences.
• Run bundle exec rake default. It executes all tests and RuboCop for itself, and generates the documentation.

Thanks for the test case! This one is open for grabs for anyone who wants to have a stab at it. 🙂

@Drenmi,

I created a pull request on top of this PR. But I got a bit confused about which base I should pick.
Should I have created the PR to this repo?

[Drenmi]

@formigarafa I think it's easiest to fork RuboCop and start from current master, manually copying over the test cases from here. 🙂

Thank you, @Drenmi.
