Restrict the train wreck for just certain situations

[Bhargav-Rao]

As I mentioned here #19 (comment):

I'd rather say that we remove the train wreck for the normal jobs which we do daily, like feedbacks. The #rekdtrain shouldn't fire when we're giving a bunch of feedback to any of the bots, either using the feedback command, or the reply option. Let the train wreck remain when a lot of people say the same general thing.

The issue which @danbopes is facing is that, they're seeing the #rekdtrain almost daily, at which point the joke becomes annoying.
