Code freeze exception request for Maps

[Marcus Lundblad <ml update uu se>]

Hi!

There's been an issue popping up latelty with Maps not being able to
access GOA when running inside a Flatpak (https://bugzilla.gnome.org/sh
ow_bug.cgi?id=779975). Even though this should hopefully be fixed in
Flatpak, this could potentially happen also when running in a non-GNOME 
environment without the GOA daemon.
So, I'd like to reuest a freeze exception for the patch in the above
bug (it will gracefully just hide the "Check in" button when creating
the GOA client fails, this is not entirely new behavior either, as this
should already happen when there is no "check in:able" account
configured in GOA). Also, there is no new translatable string in the
patch.
