In mail, changing the setting "Restrict mail templates edition and
QWEB placeholders usage" to false should remove all users but admins
from the group, including the template user.
Before this commit, you could have weird behaviou such as
1. Disable the restrictiong (group_mail_template_editor in
group_user.implied_ids)
2. Install mass_mailing (group_mail_template_editor in
group_mass_mailing_user.implied_ids)
3. Create a user test with minimum employee roles (still has
group_mail_template_editor as employee)
4. Check the box "Restrict mail templates edition and QWEB
placeholders usage"
-> test still has the template group nothing implied it
The issue was a combinaison of recomputation of implied groups

that triggered the synchronisation of groups on template user

By removing the users already in a group, we avoid falling into the
condition added at 121cd0d608 where the default user gets a
group removed, readded, hence added for everybody.
