problem when when sending 0.0, 0.0 as latitude and longitude

[kercos]

Steps to reproduce

BOT.send_location(chat_id = TEST_CHAT_ID, latitude=0, longitude=0)

Expected behaviour

Sending the location of the north pole

Actual behaviour

ValueError: Either location or latitude and longitude must be passed asargument.

Suggestion on how to solve

Do not use all function in

python-telegram-bot/telegram/bot.py

Line 1033 in 9d005d5

if not (all([latitude, longitude]) or location):

hmm,
I think we never considered that 0 is a valid alt/long.
Needs fixing, thanks for reporting
