Errors rolling back stubbed any_instance methods if they were aliases from included modules

[gmcnaughton]

If I stub out a method created by alias_method in an included module, using any_instance, the next spec to call it raises NoMethodError.

Probably related to the fix for #1042 !

This fails on ruby 2.2.3 + rspec-mocks 3.4.1, but passes in 3.4.0:

module Area
  def self.included(base)
    base.class_eval do
      alias_method(:size, :area)
    end
  end
  def area
    1
  end
end

class Circle
  include Area
end

describe Circle do
  it "stubbed" do
    allow_any_instance_of(Circle).to receive(:size).and_return(2)
    expect(Circle.new.size).to be(2)
  end
  it "not stubbed" do
    expect(Circle.new.size).to be(1) # => raises NoMethodError (!)
  end
end

Running it under rspec-mocks 3.4.1:

  1) Circle not stubbed
     Failure/Error: expect(r.size).to be(1)

     NoMethodError:
       undefined method `size' for #<Circle:0x007fc81c4f1aa0>

This bit me because I was stubbing out an alias added by acts_as_votable (this seems like a pretty common pattern for "act_as_*" libraries that don't use Concern)
