We didn't have any testing of exit codes on failure, other than checking that they were not 0. This patch changes that so we always check. Since we have the special exit code 2 (set by `clap`) for incorrect command line, I've replaced some testing of error messages by testing of just the exit code. As part of this, I also fixed `jj branch --allow-backwards` to actually require `-r` (it didn't before because having a default value means the argument is considered always provided).
