[JIRAALIGN-1495] Excel Import: Creating a new Feature/Story/ Test Case or updating an existing Feature/ Story/ Test Case's Owner via the Excel Import does not set the Owner

Issue Summary

Excel Import: Creating a new Feature/Story/ Test Case or updating an existing Feature/ Story/ Test Case's Owner via the Excel Import does not set the Owner

Steps to Reproduce

1. Import a new Story, Feature, or Test Case with an existing user's email in the Owner (assignee) field
2. Use the Excel Import to update an existing Story, Feature, or Test Case with an existing user's email in the Owner field

Expected Results

The Owner would be set on the Story, Feature, or Test Case and there would be an audit log entry of the update. Please ensure that the current import logic on whether a user can be assigned as the Owner for the specific work item persists.

Actual Results

The Owner is not set on the Story, Feature, or Test Case and there is a null audit log entry for the update

Workaround

Instead of using the email address in the import file, use the full name of the user and ignore the error on the email field in "View Info"
