Schedule persistence

If you have scheduled a job with Resque.set_schedule() for a particular configuration. Now if one changes that configuration, the change is seen once in the scheduler (view), but once the job has been queued at its schedule, the scheduler then shows the previous configuration of that schedule.

e.g.

Initial configuration

name = "export_data"
Resque.remove_schedule(name)
config = {}
config[:description] = 'This is the schedule for periodic export data as set by the user'
config[:class] = 'ExportData'
config[:args] = [domain_id, user_id]
config[:cron] = "* 23 * * *"
config[:persist] = true 
Resque.set_schedule(name, config)

Configuration which is changed later

Note the change in the config[:cron]

name = "export_data"
Resque.remove_schedule(name)
config = {}
config[:description] = 'This is the schedule for periodic export data as set by the user'
config[:class] = 'ExportData'
config[:args] = [domain_id, user_id]
config[:cron] = "1 23 * * *"
config[:persist] = true 
Resque.set_schedule(name, config)

Now when the the next time the system time is 23 hours, then the job with the configuration of
"1 23 * * "
is run, but after that the scheduler reverts to the previous configuration i.e.
" 23 * * *"
