Comment 5 for bug 1135038

One of the symptoms of this bug which some users have reported in IRC is that a OSD notification prompting the user to re-authenticate an account appears (and this is correct), but then when the System Settings UOA panel is opened, no accounts are marked as needing authentication.
This is a regression caused by the introduction of the inactivity timer in signon-ui: indeed, the process should not quit if some accounts need to be re-authenticated. I'll fix that.
