Description

Steps/Code to Reproduce

A simple cancel order fails:

rh = Robinhood(username=my_email, password=my_password, challenge_type="sms" )
# ...
# more login stuff...
# ...

# get an open order to cancel:
orders = rh.get_open_orders()
order_id = orders[0]["id"]

# attempt to cancel the order
rh.cancel_order(order_id)

Results

I expect to get any valid response form cancel_order, but instead, get the following error:

File "....../pyrh/robinhood.py", line 1475, in cancel_order
    order = self.get(urls.build_orders() + order_id)
TypeError: unsupported operand type(s) for +: 'URL' and 'str'

I believe a prior commit fixed this for a different function, just need the same fix here too.
