    [gnc-commodity.c] cache user_symbol into commodity struct
    
    Continuation of ff2ceb111 which introduced issue whereby user_symbol
    returned could become stale, leading to invalid read fixed with
    c398bef59. There are likely other user_symbol pointers becoming stale
    without this commit.
    
    This change will save the user_symbol into the commodity struct,
    avoids gchar* becoming stale.
