Penalty description is sometimes just the severity

Sometimes we have tweets like this:

2 minute minor for minor

This likely means that the secondaryType is initially just populated with the severity and then the actual penalty is added after the fact. We should verify that there is an actual penalty call prior to tweeting. If there's not, we can delay the tweet, similar to the way that we delay when the penalty taker is not present.
