TVShow().progress always return None

[dimitricappelle]

When trying to get the collection progress for a TV Show I always get None as returned value.
Tried TVShow("The Last Kingdom") and TVShow("Grey's Anatomy").

It seems that it always hits a StopIteration in core.py files (get)

try:
    return generator.send(json_data)
except StopIteration as e:
    return None
