Creation dates added to XML after editing approved records (workflow enabled)

[arhamqureshi]

Describe the bug
An additional creation date is added to the XML when a record is edited and saved with the metadata workflow enabled.

To Reproduce
Steps to reproduce the behavior:

1. Enable Metadata Workflow from the settings page
2. Go to any record and view the XML. Do a CTRL + F for "creation". There should only be one result
3. Click "Manage Record" -> enable workflow (if it isn't already)
4. Click "Manage Record" -> "Directly approve metadata" -> "Approve"
5. Edit the approved record, make a minor edit and save. There will now be a working copy of the record.
6. View the XML for the working copy and do a CTRL + F for "creation". There will be an additional creation date with the time of when the edit was saved. Once the working copy is approved, the additional creation date still does not go away.

Expected behavior
My team and I are not expecting an additional creation date and we are wondering if this is intended or not. If this is intended, is there a way to prevent the additional creation date from being added to the XML?
