Registers offenses for code such as:

module Foo
  bar end

if test
  foo
else
  bar end

and autocorrects it to:

module Foo
  bar
end

if test
  foo
else
  bar
end

Note that such offenses have been previously ignored as false positives in 4bfe82e, which resolved #7778. It mentions introduction of Layout/BlockEndNewline, but that cop doesn't handle these kind of offenses, and doesn't seem like the right place for them.

• 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.
• Ran bundle exec rake default. It executes all tests and runs RuboCop on its own code.
