Autoclosed words not reverted back via `u` key

[aliaksandrb]

Within existing nesting group the plugin leaves auto-closed end's when history reverted back via u key.

1. open an existing file, ex:

class A
  def b
   p 1
  end

  def c
    p 2
  end
end

2. Add a nested group

class A
  module B
    def x
       |
    end  # autoclosed 👍 
  end # autoclosed 👍 
  def b
   p 1
  end

  def c
    p 2
  end
end

3. Revert it back via u key multiple times. It stops in this state:

class A
  end # left 👎 
  def b
   p 1
  end

  def c
    p 2
  end
end

Please notice the end left behind. I would expect it reverts back into initial state instead.
