Failed to call refresh Apache service

Apache service should be refreshed only in correct order after tidying
mods-enabled directory. In this case better to use the 'File' resource
instead of 'Tidy' resource because last doesn't support notify mechanisms.
Also, we need to remove only 'MPM event' configuration files wich enabled
by default only on the Debian (Ubuntu) systems.
