Incorrect "No bouncing members" on a large list with small number of bouncers

[adam12b1]

Sympa 6.2.72 installed from ports/package

On a large list (thousands of members) with only a handful of bouncers, the Bounces page incorrectly shows "No bouncing members", because the bounce_rate rounds down to zero. It should use bounce_total instead.

So, in reviewbouncing.tt2, change bounce_rate to bounce_total in this code:

[% IF bounce_rate %]
    <a class="actionMenuLinks" href="[% 'export_member' | url_rel([list,'bounce']) %]">
        [%|loc%]Dump[%END%]
    </a>
