Forbidden stacktrace when getting info in DM

[Gillingham]

Steps to reproduce.

1. Create a poll, I'm not sure it matters but the one I created as anonymous.
2. DM the bot pm!show <poll>
3. Click the info ? on the bots response.
4. You correctly get the info for the poll, but it also causes the below stacktrace.

Task exception was never retrieved

That is caused because the bot cant remove user reactions in DM channels.
I will fix it with the next release, but this is nothing to worry about, you can just ignore the errors.
