For 1.0.3 of capistrano-sidekiq, indices or processes are changed by rolling-restart

[unclok]

Because we're not using neither of upstart or systemd, my team is still using 1.0.3. The problem is each_process_with_index(reverse: true). If we use rolling-restart from 1.0.3, pid_files has been loaded reverse direction. But because the function is using each_with_index, index attached in the list is not reverse direction, so pid_file and idx are not matching in this case. Also, because this behavior overwrite the PID inside of the pid_file, half of previous process lose it's pid file and remain forever.

This is easy to fix (just change reverse:false to reverse:true), so I'll make a pull request soon.
