LiveChat duplicate key error, when guest tries to use same username/email

[tuudik]

Steps to repro:

1. Open live chat (incognito browser window) and register: user name / user.name@name.com
2. Write something
3. Close incognito browser window and open new
4. Re-register with same user credentials as in step 2
5. Internal Server Error

Before this one, deleted old guest users and when registered in LiveChat (related #1824 (comment)):
