Append ShellUtil::GetUserSpecificRegistrySuffix() to the base appid.

I assume the app launcher shortcut won't be per-profile (i.e. that profile
switching will be in the app, just as in Chrome); otherwise you should look into
ShellIntegration::GetAppModelIdForProfile() although that doesn't yet handle
user suffixes since it's only used as a runtime property now).

From F2F, append => string contatenation (not push_back()).  Done.
