Steps to reproduce:

1. Clone git@github.com:linzhp/go_examples.git to GOPATH
2. Run mockgen -package core -self_package github.com/linzhp/go_examples/interfaces github.com/linzhp/go_examples/interfaces Methods

What do I expect:

The generated mock should not import github.com/linzhp/go_examples/interfaces because it is specified in -self_package

What do I see instead:

import (
	gomock "github.com/golang/mock/gomock"
	interfaces "github.com/linzhp/go_examples/interfaces"
	reflect "reflect"
)
