Title: Rescue BCrypt Invalid Hash in migration strategy

Because it's possible for someone to enter an incorrect SHA1 password, we need to do something about the Invalid Hash error that's raised when it goes to the BCrypt authentication step. I chose to rescue the InvalidError hash error only in the migration strategy.

Let me know if there is a better way that you want me to add in instead.
