Fix resolving object from request with overridden uri

I can't edit PR so created new one.
This is old with conversation: #163

Hey @MisterBolt!
Just getting around to give this a proper look, but could you help give a bit more context?
Maybe add a test that would fail on main?

There is an existing test that suggests this should already be working, so I'm wondering what issue you were seeing:

spyke/test/custom_request_test.rb

Lines 5 to 10 in f49174b

	def test_custom_get_request_from_class
	endpoint = stub_request(:get, 'http://sushi.com/recipes/recent').to_return_json(result: [{ id: 1, title: 'Bread' }])
	recipes = Recipe.with('/recipes/recent').get
	assert_equal %w{ Bread }, recipes.map(&:title)
	assert_requested endpoint
	end

The main difference from the code you shared is the new call (which I'm not sure how is being used in the example):

    def self.create(params)
      with("fcc-add-records").new.post(params)
    end

    def self.update(params)
      with("fcc-update-records").new.post(params)
    end
