why do we need this member now here?

I wanted to have a single instance of the installer, even though the component
can get re-registered.  The single instance is to ensure that there is just one
PnaclProfileObserver.  Also the PnaclProfileObserver needed to be created
"early" to observe the user logins, since the component isn't registered until
after login.
