Subject: [PATCH] Fix assertion violation when editing an admin.
There is a possibility that an EditAdminBox will be shown for someone
who can't add admins right now (in case server says he can edit one).
In that case assertion about the admins checkbox is false and we fix
that. Currently server sometimes does return this flag by mistake.
