Change find method in case history action

[rlgreen91]

In the history action in the cases controller, change the find method from find_by_slug to find. This should also allow you to remove the check for this_case.blank? in the conditional.

Hey, I would be happy to do that!

@birtony Sounds great! Please feel free to assign it to yourself. As a quick note, I don't think this will count for Hacktoberfest until October, so I'll probably hold off review until then so you can get your point.

@rlgreen91 alright, thank you!
