Discord bot should detect a ✅ in #get-help

[BNAndras]

Within #get-help, it'd be useful if the bot could apply ✅ to a thread if that reaction has already been added by a user. In the thread list view, Discord only shows the most used reaction for a thread and in a tiebreaker, it seems to go with the first applied reaction. When the thread is created, the bot applies a track reaction if detected so if the user adds the checkmark reaction, the track reaction is shown first because both have been applied once. So if the bot seconds a checkmark, that should break the tie and show the checkmark, not the track reaction. Of course if someone seconds the track reaction, it'd still be a tie if the bot seconds the checkmark, but that doesn't appear very common in recent threads.

The simpler option might be to have the bot prefix "[SOLVED]: " to the thread title if the checkmark is detected. That'd be less fragile.

In theory the bot isn't supposed to react on get help threads. That's clearly not working right.
