collections.get_store is not working as documented

[realslimshanky-sh]

Upon going through collections doc we see 2. call .get_store(<somename>) to create or access the named collection you want (the collection will be created automatically if it doesn't exist) ; you get a "store" object back,
But when you try this

>>> store = collections.get_store('store_which_does_not_exist')
>>> store.get('key_which_does_not_exist')
DEBUG:https://storage.scrapinghub.com:443 "GET /collections/462630/s/store_which_does_not_exist/key_which_does_not_exist HTTP/1.1" 404 46

*** scrapinghub.client.exceptions.NotFound: unknown collection store_which_does_not_exist

When we .set some value to store which doesn’t exist, store is created and then the values are stored.

>>> store.set({'_key': 'some_key', 'value': 'some_value'})

According to docs, shouldn’t the store be created when we call .get_store ?
