`users` field type in dropdown mode can't search by email

[edalzell]

Bug description

We have a users field in a fieldset in default drop-down mode. Most of the users don't have names, only emails. In the drop down you see a mix of names and emails because some users do have name but those that don't fallback to email.

However you try to find a user by e-mail (because you can actually see it in the list), it's not found.

How to reproduce

1. users fieldtype
2. have users with only email
3. see the users in the drop down
4. search for one of them by email

The workaround is use typeahead mode as that searches the email field as well.
