Lint/MissingSuper does not handle dynamically-generated classes

[vlad-pisanov]

Currently, Lint/MissingSuper doesn't seem to handle classes generated dynamically via Class.new:

Class.new do
  def initialize; end # no offence ✔️
end

Class.new(String) do
  def initialize; end # no offence ❌(inherited from String -> should call super)
end

class X
  Class.new do
    def initialize; end # no offence ✔️
  end
end

class X < Y
  # X is inherited, but this class isn't -> we shouldn't have to call super
  Class.new do
    def initialize; end # Lint/MissingSuper: Call super to initialize state of the parent class ❌
  end
end
