[Mac, Win] Only show the user manager tutorial if "See what's new" is clicked.

- remove the profile preference that used to keep track of showing the
tutorial any time the user manager was shown for a particular profile.

- show the upgrade bubble for local profiles as well (so that local profiles
have a chance to see the tutorial)

- for the local profiles upgrade bubble, don't show the "Not you?" link as
it doesn't really make sense.
