Original issue's description:
> [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.
