Zero values in trackers gives 'missing tracker' error

[shannonfenn]

I'm not sure if non-string values are supposed to be supported but the following:

app.notify(event_name='test', trackers={'name': '<name-here>', 'time': 40.1, 'warnings': 0, 'notes': '<some notes>'})

fails with:

{'error': True, 'msg': '{warnings} is a missing tracker', 'status': 401}

while it succeeds if the value of warnings is changed to a non-zero value.

Since the issue also occurs with empty strings, None, False, 0.0 etc. so I assume there is the equivalent of a bool() check in the incoming values on the other end.

Is there anything fundamentally preventing empty strings, False or zero values being sent through the REST API?

I know this isn't a problem with this python wrapper but I'm not sure where else to send this issue.
