Reset not only whitespaces but comments too.

The logic to backtrack to the last non-whitespace on the previous line should also backtrack comments. Otherwise the following example would be generate a warning that the ensure line is indented to fare.

class () {
  file {
    'this': #comment
      ensure  => 'present',
  }
}

Nice catch, thanks! I'll release an updated gem later today.
