Bug#733979: apache "a2dismod cgi" fails with mpm-worker and mod-fastcgi installed

[Denisa Oravcova]

Similar, although not the same, situation here.

Since both the a2enmod and a2dismod scripts follow the same logic:
    if  ( module to enable/disable is cgi   &&   MPM is threaded (worker) )
    then cgid is enabled/disabled instead

I think, we should be disabling cgi module *BEFORE* apache2-mpm-worker is
installed.

I failed to do so, therefore disabled mod cgi manually:

$ sudo rm /etc/apache2/mods-enabled/cgi.load
