Add Email Id to Employee Name when choosing Overriding Approver

Summary:

When user submits an expense claim and search the name of override approver, results only return with person name without additional information. If there are multiple people with same name, user cannot distinguish difference of all person name without any other identifier.

We need to understand if the email id can also be added to Overring User's Name so that Expense can be submitted to the correct person as without it is causing a lot of confusions for the users.
