    google: Fix crashes when deleting if the file isn't found
    
    Currently in delete operation, if the entry gets resolved but parent
    resolution fails, the jump to `out` label (while handling error) will
    cause the existing entry's ref_count to decrease by 1 (since `out`
    label calls g_object_unref on entry).
    
    We fix the issue by removing g_object_unref from `out` label and
    suitably unreffing the entry.
