Typo: features_weight.initializer is run twice

self.sess.run([self.features_weight.initializer, self.features_weight.initializer])

Hey, seems like ref_img_features remain uninitialized, features_weight inited twice instead.
PS: If corrected - the first iteration yelds zero vgg loss, but that might be because I messed something else (trying to use facenet instead of vgg). but might be not _

I'm not sure if or why it needed to run twice, but this is at least an original bug/feature from @Puzer
