Facenet: model_checkpoint_path is None

[skrew]

Hi,

In facenet.py, line 381,

ckpt_file = tf.train.get_checkpoint_state(model_dir).model_checkpoint_path

AttributeError: 'NoneType' object has no attribute 'model_checkpoint_path'

See #40

the get_checkpoint_state(mode_dir) function needs a checkpoint file, by default 'checkpoint' in the model directory, with the in #40 described content.

Thanks @lodemo!
I will probably remove the use of get_checkpoint_state in the future since it requires this annoying little file.
