Issue Summary

The /issue/createmeta endpoint doesn't respond with the parent field when the project issue type scheme doesn't contain epic

Steps to Reproduce

• Create a project and associated issue type scheme
• Remove the "Epic" issue type from the issue type scheme
• Make a call to the `issue/createmeta` endpoint with `expand=projects.issuetypes.fields` included in the query params

Expected Results

• Both the `epic_link` and `parent` field are returned for base level issue types

  Actual Results

• Only the `epic_link` field is returned

  Workaround

Where this is causing issues, please include the Epic field in the issue type scheme to ensure both fields are returned
