[pyramid] Avoid shutting down the repository at exit if it's already shutting down For install `cubicweb-ctl pyramid` command will explicitly call `repo.shutdown()` so the atexit hook is redundant. Prevent the latter to be executed when the repository is already shutting down (otherwise one gets an assertion error).

#!/bin/sh -e

if [ "$1" = "purge" ] ; then
        rm -rf /etc/cubicweb.d/
        rm -rf /var/log/cubicweb/
        rm -rf /var/lib/cubicweb/
fi
