Can open it with “gnome-control-center online-accounts” from a console (although there are two warning message, see below), but that's not clean to have to open a console to open it. I came to that issue while learning more about Ubuntu WebApps.
Additionally, opening the missing control panel from a console, I get these two messages:
** (gnome-control-center:10977): WARNING **: Could not find settings panel "online-accounts"
** (gnome-control-center:10977): WARNING **: Could not load setting panel "online-accounts": Unknown error
Same for me, using Ubuntu Precise 12.04.
