[stability] App turned to `creating` status

[Jimmy Chu]

Refer to the attached sql and log package.

• sql: https://www.dropbox.com/s/ab26ymloxezjtnt/prod-db-201506191709.sql?dl=0
• log: https://www.dropbox.com/s/ew6nb9ggr4yudz3/log-201506191219.tgz?dl=0

The app with id: 487 is stayed at creating status. The reason maybe related to creating a mysql service and then stopping the service which returns a 500 response from openshift. Refer to delayed-job.log from line: 481 - 530.

fix: Must set pending status before running backend jobs, otherwise it will revert to nil when error (fixing #215)
