move: *.dvc file not moved with target file
0.23.2

using move command does not move .dvc file, and it should.

Test:
```
class TestMoveFileToDirectory(TestDvc):
    def test(self):
        foo_dvc_file = self.FOO + ".dvc"
        ret = main(["add", self.FOO])
        self.assertEqual(ret, 0)
        self.assertTrue(os.path.exists(foo_dvc_file))

        new_foo_path = self.DATA_DIR+"/"+self.FOO
        new_foo_dvc_path = new_foo_path + ".dvc"
        ret = main(["move", self.FOO, new_foo_path])
        self.assertEqual(ret, 0)

        self.assertTrue(os.path.exists(new_foo_path))
        self.assertTrue(os.path.exists(new_foo_dvc_path))
```
last assert fails.
