seems to not account for when a review has been dismissed

[sam-github]

example: nodejs/node#10747

I just encountered that and patched it yesterday 😄.
Just opened PR #15

Looks like it still doesn't handle nodejs/node#14782 when someone dissmised their own reviews

Funny enough, it also tries to delete my review (not that I have approved or rejected at that point) from the map when I added a reference with a title containing "dismissed" lol

Looks like @joyeecheung fixed this in #16 (but it can be reopened if that is not the case).
