Get bot username from API

[bkeepers]

probotUsername is currently hardcoded in defaults.json:

probot-snooze/etc/defaults.json

Line 2 in f87c9ba

"probotUsername" : "probot-snooze[bot]",

This causes it to not find comments from the app when thawing, which I believe is causing #8.

GET /app will get details from the currently authenticated app. This endpoint isn't supported yet in node-github, but I'll get a PR open for it once octokit/octokit.js#568 is merged. Once it is, I think the app should call this endpoint on startup to get its own name.

wow, that's awesome. a bit buggy that you would always have to use the same probot snooze instance or else this would fail (maybe add instance_id in my magic data section so I can do a quick compare if i don't find anything for fallback?)

This is much cleaner and less string.compare-y. Like it, great suggest!

this is now merged. should this become a part of upstream? robot.user or some sort?
