Methods with ... params generate broken mocks.

[shawnburke]

This is a regression sometime since SHA a43d734f241595. Not sure exactly when.

The following interface will generate a mock that doesn't compile:

 type MyInterface interface {
   WriteItems(uuid string, values ...string) error
 }

The old "working" code generated code that probably wasn't mockable, but it wasn't blocking.

This generates:

func (_m *MyInterface) WriteItems(uuid string, values ...string) error {
ret := _m.Called(uuid, values)
var r0 error
if rf, ok := ret.Get(0).(func(string, ...string) error); ok {
    r0 = rf(uuid, values)
} else {
    r0 = ret.Error(0)
    }
return r0
}

Which results in:

 mocks/MyInterface.go:14: cannot use values (type []string) as type string in argument to rf

I think Line 14 needs to be:

        r0 = rf(uuid, values...)
