Added load method to class gensim.models.wrappers.fasttext.FastText to set self.wv.syn0_ngrams (present in newer models) using self.wv.syn0_all (present in older models).

Relevant issue : #1642

What's with this setattr / delattr? Why not a simple (and more readable) model.wv.syn0_ngrams = model.wv.syn0_all?

self.assertEqual(loaded_model.wv.syn0.shape[1], 10)
self.assertEqual(loaded_model.wv.syn0_ngrams.shape[1], 10)
