Displays the handles of users that reacted on issues and pulls, in addition to the counts. Closes https://tangled.org/@tangled.org/core/issues/246
There's a couple ways to do it
- Doing the db query in 1 roundtrip -- that's what I did here
- Doing 2 db queries, 1 for the count and 1 for the usernames
If we prefer (2), or another route, that's fine, I can change it.
