Describe the bug

When using multilink, if the transport is dropped because of net failure or crash, only one link reconnects.

To reproduce

1. Start first router: RUST_LOG=debug ./target/debug/zenohd --cfg=transport/unicast/max_links:2 -l "tcp/[::]:7447?rel=1;prio=0-3" -l "udp/[::]:7447?rel=0;prio=4-7"
2. Start second router: RUST_LOG=debug ./target/debug/zenohd --cfg=transport/unicast/max_links:2 -l "tcp/[::]:7448?rel=1;prio=0-3" -l "udp/[::]:7448?rel=0;prio=4-7" -e "tcp/127.0.0.1:7447?rel=1;prio=0-3" -e "udp/127.0.0.1:7447?rel=0;prio=4-7"
3. See in the log that both links established.
4. Kill first router.
5. Restart first router.
6. See in logs that only one link reestablished.
