Post function to set security level based on project role for initial transition is not working

Issue Summary

Adding a post function to set a security level based on the reporter project role would set the correct security level selected, but it is not working.

Steps to Reproduce

1. Access a company-managed project and click on Project Settings > Workflow > Edit workflow
2. Click the initial transition and click to add a Post Function
3. Add a post function: Set issue security level based on user's project role and set one project role and one security level
4. Publish the workflow
5. Create a new issue with a user that has the role set on the Post Function

Expected Results

An issue be created with the security level set at the post function.
