Moving Epics from a team-managed project to a company-managed project lose their Epic Name

Issue Summary

When trying to migrate Epics from next-gen project to a Classic project, you are forced to enter a value for 'Epic Name' in the Bulk edit screen. This gives all Epics that name once they are moved to the Classic project.

Steps to Reproduce

1. Create some epics in a next-gen project
2. Use the Bulk Edit feature in Issue Navigator
3. Move the issues to a classic project
4. Check the 'retain' checkbox next to each of the fields for the Classic epic
5. When you submit this form, you are told the field for the Epic Name is required and you must submit a value
6. Enter a value
7. All Epics have that same value applied

Expected Results

The Epic Name is retained when moving from Classic to Next-gen

Actual Results

All the Epics have the same Name once migrated.

Workaround
