Handle Leader rerolls for Loners

[IBBoard]

In Replay_2020-09-06_10-13-12.txt, we get an error because it performs a Loner check but a Leader reroll. The Leader reroll is a skill and so shows up before the Loner. We need to handle this, since we normally rely on the commands to see what happened.

It might help to parse all reroll entries (which may also help with some kickoff results that grant extra rerolls).
