Fix tests for fastcgi

The fastcgi server define wasn't including apache::mod::fastcgi, but
this is idempotent and required, since it declares a dependency on
Apache::Mod['fastcgi'].

I also cleaned up some linting things and put the notify on the service
class instead of the service resource (as is the newer pattern).
