GUID parsed from cab is incorrect

[superm1]

I've been slowly bringing up a new system to test with UEFI capsule. I've gotten everything working properly with fwupdate now, but fwupdmgr isn't working with it properly. It doesn't think that the GUID in the cab is appropriate to flash on the system.

It seems that fwupd is parsing the wrong guid the same way that appstream-glib (hughsie/appstream-glib@680d47f). Here's some (cleaned for private info) debug info:

 $ fwupdmgr get-devices 
Device: UEFI-6180aaaa-5529-4bbf-b4fd-65b4f788de5b-dev0
  Provider:        UEFI
  Guid:            6180aaaa-5529-4bbf-b4fd-65b4f788de5b
  Version:         2
  Internal:        True
  AllowOnline:     False
  AllowOffline:    True

$ fwupdmgr get-details platform.cab

Actually never mind - this was because fwupd was running in background from before appstream-glib was updated.
