Issues with mocking packages that have mix of ref and copy funcs

[joesustaric]

To reproduce this try the following.

File Testpack\testpack.go:

package testpack

type TPStruct struct {}
//func (t TPStruct) Method() {}  //Uncomment this line to produce error
func (t *TPStruct) PointerMethod() 

file wmscratch\wmscratch.go:

package wmscratch

import "testpack"

func PointerFunction(t *testpack.TPStruct) {
    t.PointerMethod()
}

Test file Wmscratch\wmscratch_test.go:

package wmscratch

import (
    "testing"
    "testpack" //mock
    "github.com/golang/mock/gomock"
)

func TestSumSqrt(t *testing.T) {
    ctrl := gomock.NewController(t)
    defer ctrl.Finish()

    testpack.MOCK().SetController(ctrl)

    tp := testpack.TPStruct{}
    tp_ptr := &tp

    tp_ptr.EXPECT().PointerMethod()
    PointerFunction(tp_ptr)

}

Uncommenting the func (t TPStruct) Method() {} in the TPStruct package:

controller.go:113: no matching expected call: *testpack.TPStruct.PointerMethod([])
controller.go:158: missing call(s) to testpack.TPStruct.PointerMethod()
