Python 3 issue fix - dict_values does not support indexing

[Barqawiz]

There is an issue with calling following code in Python 3+:
self.embeddings_index.values()[0]

Reason
In Python 3, dict.values() does not return list and following error will be raised:

dict_values does not support indexing

Solution
The line should be updated in python 3+ as following
list(self.embeddings_index.values())[0].shape[-1]
In following files:

• token_model.py
• embeddings.py

This still gives an error for the sentence_model.py:

---> 37 self.embeddings_index = get_embeddings_index(embedding_type)

TypeError: 'dict_values' object does not support indexing

It is not clear where exactly in token_model.py and embeddins.py the correction should be applied.
