[open_channel & restart] restart fiber failed when stopping at sending open channel

[15168316096]

Multi-hop fiber1 <-> fiber2 <-> fiber3 Restart our node: fiber1 restarts during the process of sending openchannel. At this time, the status of the channel is still in the intermediate state, not the ready state. Then we restart fiber1 and find that the status cannot be updated to ready. The script execution does not return to the ready state.

raise TimeoutError(
            f"Channel did not reach state {expected_state} within timeout period."
        )
E       TimeoutError: Channel did not reach state CHANNEL_READY within timeout period.

Restarting ckb cannot restore it to the ready state.
