Odd exception in repo_helper for pygithub3

In line https://github.com/LanceMaverick/skybeard-2/blob/skb-dev/beards/repo_helper/python/repo_helper/__init__.py#L43 it complains about not finding github.GithubException.UnknownObjectException after raising github.GithubException.UnknownObjectException.

Very curious.

It may be worth abandoning the pygithub3 dependency for this beard in favour of raw aiohttp anyway to avoid this. (fewer dependencies, fewer problems.)
