next_token fix for VendorOrders

[AndreiFAD]

Hi!

Describe the bug I never get the next page. It only worked for me with the following solution(picture) (I made a fork, about the modification) https://github.com/AndreiFAD/python-amazon-sp-api/tree/next_token -> https://github.com/AndreiFAD/python-amazon-sp-api/commit/73c89216dbf7e6e1f31c0d7cfb54756f66727312

from sp_api.util import throttle_retry, load_all_pages

@throttle_retry()
@load_all_pages()
def get_purchase_orders(**kwargs):
    """
    a generator function to return all pages, obtained by NextToken
    """
    return VendorOrders(credentials=get_amz_credentials(profile_name), marketplace=Marketplaces.XX).get_purchase_orders(**kwargs)

df_list = []
for item in get_purchase_orders(createdAfter=(datetime.now() - timedelta(days=20)).isoformat()):
    df_list.append(pd.DataFrame.from_records(item.payload['orders']))
df = pd.concat(df_list)

Thanks for reporting this. Can you create a PR to account for this?
