Order of operation issue with _unmarshal_json_object

[moilanen]

During an unmarshal the attribute_name was getting set to an empty string. Looks to be an order of operation issue w/ the string append.

Hey @moilanen thanks for contributing to this repo. The change you're proposing makes sense but do you mind show an example input as well as a before and after output? We are currently working on fixing our CI system, otherwise a test would be more appropriate.

Sure thing. I'm on Python 3.7.5 on Mac.

Here's my test and results:

from polygon import RESTClient

def main():
    key = "APIKEY"
    client = RESTClient(key)

    resp = client.stocks_equities_aggregates('AAPL', 20, 'minute', '2019-12-25', '2020-01-02')
    print(str(resp.ticker))

if __name__ == '__main__':
    main()

Before:

$ python test.py
Traceback (most recent call last):
  File "test.py", line 11, in <module>
    main()
  File "test.py", line 7, in main
    print(str(resp.ticker))
AttributeError: 'StocksEquitiesAggregatesApiResponse' object has no attribute 'ticker'

After:

$ python test.py
AAPL
