clauseValues is empty when Starting Sprint

Steps to reproduce

1. Install JIRA and Agile
2. Create a new project and Scrum Board (Sample Scrum Board can be used as well)
3. Create issues in this board
4. Configure the Board to use Remaining Estimate and Time Spent for Time Tracking (Board > Configure > Estimation)
5. Create Sprint 1
6. Drag issues to this sprint
7. Create Sprint 2
8. Delete Sprint 1
   • All issues in Sprint 1 will automatically be moved to Sprint 2
9. Start Sprint 2

Expected behavior

1. The Sprint starts normally

Actual behaviour

1. A red pop up message saying clauseValue is empty will appear
2. 
3. The following thrown in the logs

Environment

• Tested with JIRA 6.3 and Agile 6.7

Workaround

This only happens when issue is automatically added to a new sprint when the first sprint is deleted. The workaround would be to explicitly drag the issue to the desired sprint

• Manually drag all issues from Sprint 1 to Sprint 2 before deleting Sprint 1
  • Sprint 1 should be empty when it is being deleted
