ClassAndModuleChildren incorrectly flags classes with a single method

[CyborgMaster]

I like the compact style of class and method definition and therefore have the following in my .rubocop.yml:

ClassAndModuleChildren:
  EnforcedStyle: compact

However this erroneously flags the following module:

module TimeCopMinitestPlugin
  def after_teardown
    Timecop.return
    super
  end
end

with this offense message:

test/test_helper.rb:19:8: C: Use compact module/class definition instead of nested style.
module TimeCopMinitestPlugin
       ^^^^^^^^^^^^^^^^^^^^^

It seems as if it is detecting that the class has a single child and therefore prompting me to try and combine it. This works for classes/modules with a single inner class/module, but is impossible when the contents is a method.

The offense should not be reported if the single child is not a class/module.

Yep, this definitely looks like a bug.

Glad to know it's not just me :-)

I can take a look, if you like.
