v-restore-user won't create MySQL user under Ubuntu 16.04

[fengkaijia]

Operating System (OS/VERSION):

Ubuntu 16.04

VestaCP Version:

0.9.8-17

Installed Software (what you got with the installer):

bash vst-install.sh --nginx yes --apache yes --phpfpm no --vsftpd yes --proftpd no --exim yes --dovecot yes --spamassassin no --clamav no --named no --iptables no --fail2ban no --mysql yes --postgresql yes --remi no --quota no

Steps to Reproduce:

1. Run v-backup-user xyz on a Debian 8.0 instance;
2. SCP the file to the new Ubuntu 16.04 instance;
3. v-restore-user xyz xyz.2016-11-26.tar
4. MySQL SELECT * FROM mysql.user will found no entry start with xyz

Other Notes:

If I go to https://vestacp:8083/edit/db/?database=xyz_abc, I can view and edit the password for the missing user, and then the user appear again.
