 `command_process_create_cell` tries to check several conditions and can to
 call `channel_send_destroy` for already exist circuit.
 `channel_send_destroy` is more complex mechanism than sending of some cell
 as it happened before.
 It shouldn't to call `channel_send_destroy` if `circ_id` already exist for
 `chan`. It should to check `circ_id` and drop if already exist and only
 then to check all another stuff.
