calculate_average_kda example issues

Fixed the typo.

@robrua, if a call fails in exectue_request then None gets returned right? What does "fail" mean in this case? Should this instead raise an exception?

[robrua]

In this case stats[StatSummaryType.ranked_fives].stats is returning None, so querying it for kills is impossible.

This is the intended behavior - we shouldn't be creating an AggregatedStats object if Riot doesn't send one, and if we started raising exceptions whenever one piece of data is missing you couldn't ever finish a call without an exception.

I think we should just change the example to StatSummaryType.normal_fives for now, as that doesn't cause the same problem and should be more robust to season/name changes that might break the example
