DVCS presents wrong webhook migration status for linked account/organisation

Issue Summary

This is reproducible on Data Center: YES

Steps to Reproduce

1. Git Client - create organisation including 2 repositories 
2. In git archive one of repositories
3. Link organisation to Jira via DVCS Connector plugin
4. Wait till organisation get linked and DVCS Connector install webhooks remotely (one repository should be marked as SECURED, second one as FAILED). Webhook migration status for particular repository you can check by going to DVCS Accounts -> go to interested organisation to see each repository webhook status.
5. Ensure in the view of DVCS Accounts organisation has FAILED webhook status.

7. Go back to the view of DVCS Accounts

(After those steps, organisation contains only one SECURED repository)
