Users without Email could not be found in the share entry box

[imthemichi]

What is going wrong? What did you observe?

Describe the bug

I have a user, which has no Email-Address in his profile. If I search for this user or even if a search contains this user (other users could have an email), nothing is returned in the search result.

Steps to reproduce the behavior

1. Go to 'a Poll'
2. Click on 'share'
3. Search for a user without an email address (username: oemail)

How should it work?

What you expected to happen?

The user is returned in a submenue and can be selected for sharing.
