Bug Description

If we set a user's quota to 0 it throws an error:

[WAR] bb (admin/users/edit.php:356) Division by zero
Call stack (most recent first):

    log_message("Division by zero", 8, true, true, "/home/robertl/htdocs/mahara-devel/mahara/htdocs/ad...", 356) at /home/robertl/htdocs/mahara-devel/mahara/htdocs/lib/errors.php:439
    error(2, "Division by zero", "/home/robertl/htdocs/mahara-devel/mahara/htdocs/ad...", 356, array(size 7)) at /home/robertl/htdocs/mahara-devel/mahara/htdocs/admin/users/edit.php:356

Normally we wouldn't be setting a user's quota to 0 - but for automated tests this can make sense.

So it is useful to fix for that reason.

Noticed when running webservices phpunit tests
