Slack groups cause frequent "Unbound slot" errors

[ieure]

Describe the bug

I see regular errors:

error in process sentinel: Unbound slot: slack-group, "#<slack-group slack-group-156f878f1a74>", id, oref

To Reproduce Steps to reproduce the behavior:

I'm not sure. It happens intermittently & seems to depend on what others are doing on Slack, rather than what I'm doing.

Expected behavior Emacs-Slack shouldn't be accessing unbound slots.
