[BUG] Generated tests in Go Client have bad type when non-primitive type used in PATH

Description

Generated tests in Go Client don't properly reference non-primitive types for parameters it seems.

Generated Go Code is currently:

func Test_tea_client_TEAProductAPIService(t *testing.T) {

	configuration := tea_client.NewConfiguration()
	apiClient := tea_client.NewAPIClient(configuration)

	t.Run("Test TEAProductAPIService GetTeaProductByIdentifier", func(t *testing.T) {

		t.Skip("skip test")  // remove to run test

		var productIdentifierType TypeProductIdentifierType

		resp, httpRes, err := apiClient.TEAProductAPI.GetTeaProductByIdentifier(context.Background(), productIdentifierType).Execute()

		require.Nil(t, err)
		require.NotNil(t, resp)
		assert.Equal(t, 200, httpRes.StatusCode)

	})

var productIdentifierType TypeProductIdentifierType should be var productIdentifierType tea_client.TypeProductIdentifierType

Suggest a fix

I'll work on a PR to address this.

Start by reproducing the generated Go client tests using the OpenAPI declaration and the Docker command in the issue, with spec/generators/go.yaml. Inspect how path parameters referencing non-primitive schemas are rendered in the generated test, then verify that the qualified type is emitted and the generated test compiles.
