Fix GitHub rendering for posts without authors (#341)

Browse Source 
Our GitHub renderer tries to display the author name for a comments or
pull request reviews. However, as we've already discovered (#228), not
every GitHub post has an author available. This breaks attempts to demo
the v1 cred explorer on some interesting repos, e.g. ipfs/js-ipfs.

Since the v1 code is all deprecated, it's effectively a demo branch
pending a rewrite of the cred explorer to use the v3 graph. As such, I
didn't include unit tests.

Test plan:
Attempt to run the cred explorer on `ipfs/js-ipfs` prior to this PR.
Observe that it loudly fails. Attempt to run it after this PR, and
that it succeeds.
