Prevent automatic issue generation

[mikevespi]

Currently, Zenhub seems to create a new ticket when a PR is created. Since we create tickets prior to beginning work, we end up with duplicate tickets. Closing the generated issue also closes the attached PR.

This is likely the product of a setting in either GitHub or ZenHub.

If this issue is not being experienced by all developers, then a meeting should be set to walk through the workflow with any developers who are experiencing the issue.

DoD:

• Investigate whether all devs are experiencing this behaviour
• If yes:
  • Update settings where applicable to prevent PR creation from generating an issue
• If no:
  • Set a meeting with devs who are experiencing the issue to demonstrate the successful workflow
