[gnome-online-accounts/gnome-3-20] goa_identity_manager_get_identity_finish should return a new ref

[Debarshi Ray <debarshir src gnome org>]

    goa_identity_manager_get_identity_finish should return a new ref
    
    The vast majority, if not all, of *_finish functions out there transfer
    ownership of the return value to the caller. This also matches with the
    behaviour of new APIs like g_task_propagate_pointer. Therefore, let's
    make this change for the sake of consistency and making it easier to
    port to GTask.
