beta: dont restart apache on fake mwsync

Apache is not launched on applicationserver start to prevent having it
serve pages using an old version of MediaWiki.  Instead we run a sync of
the MediaWiki files and notify the Apache service to make it running.

In labs, we do not use syncing (/bin/true). Whenever puppet runs it ends
up notifying the apache service and restarting it:

notice: /Stage[main]/Applicationserver::Config::Apache/Exec[Fake sync
apache wmf config on beta]/returns: executed successfully
info: /Stage[main]/Applicationserver::Config::Apache/Exec[Fake sync
apache wmf config on beta]: Scheduling refresh of Service[apache]

This patch prevent the Exec[Fake sync apache wmf config on beta] to run
whenever there is a process named apache2.

I am not sure what the behavior in production so I left it untouched.
