Error when requestContext is None

Description

I have a lambda that is called through API Gateway, but can also be invoked directly via a lambda client. Upgrading to 2.12.0 started causing this error when invoked via client.

[ERROR] TypeError: argument of type 'NoneType' is not iterable
Traceback (most recent call last):
  File "/var/task/apig_wsgi/__init__.py", line 61, in handler
    if "requestContext" in event and "elb" in event["requestContext"]:

This is being done from Kotlin code, using com.amazonaws.services.lambda.AWSLambda client. When an AwsProxyRequest object is constructed, it has requestContext=null by default. This results in the error above.

I can update my invoke code to set a dummy requestContext, but I do believe it is valid to be None in the direct lambda invocation use case. Does it make sense to add a not None check here for requestContext?

Thanks.

Indeed it makes sense to add the check. Fixed in #290, released in 2.12.1.
