Fix tensordot with list of ints as axes (#11959)

* Fix tensordot with list of ints as axes

This fix tries to fix the tensordot issue raised in 11950 where
```
TypeError: object of type 'int' has no len()
```
is thrown out when the axes is a list of ints:
```
with tf.Session() as sess:
    sess.run(
         tf.tensordot(tf.ones((3,3), dtype=tf.float32), tf.constant([2, 3, 1], dtype=tf.float32)[None, None], axes=[1, 2])
    )
```

In numpy it is possible to specify `np.tensordot(np.ones((3,3)), np.array([2, 3, 1])[None, None], axes=[1, 2])`

This fix fixes #11950.
