Installer: Spurious "service account ... not removed" on uninstall

Hi folks

A Stack Overflow user noticed that the EDB installer for PostgreSQL
emits the message:

"The data directory (bla bla....) and service user account (NT
AUTHORITY\NetworkService) have not been removed"

when 9.2 is uninstalled. They were quite confused by this. It occurs to
me that if the standard NetworkService account is used, it'd be good to
suppress the user account not removed part of the message entirely.
