Bug#849509: popularity-contest installed momentarily even if user says No

[積丹尼 Dan Jacobson]

Well just as if one's country must install a missle defense system just
to ask the question if they should install the missle defense system...
and then remove the missle defense system...
But OK maybe there are some translation strings unavailable from e.g.,
$ for package in popularity-contest; do grep-aptavail -PX -d $package;
  echo should we install...; read answer; ... done
