v1.0 light node cannot sync to the newest block

[guoxbin]

Seems that v1.0 light node doesn't work. It cannot sync to the newest block. Apologies if I misunderstood.

Reproduction steps

• run Alice full node
  cargo run -- --base-path /tmp/alice --chain=local --alice --node-key 0000000000000000000000000000000000000000000000000000000000000001 --telemetry-url ws://telemetry.polkadot.io:1024 --validator --log="sync=trace"

• run Bob full node
  cargo run -- --base-path /tmp/bob --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN --chain=local --bob --port 30334 --telemetry-url ws://telemetry.polkadot.io:1024 --validator --log="sync=trace"

• wait alice and bob generate some new blocks

• run Charlie light node
  cargo run -- --base-path /tmp/charlie --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN --chain=local --charlie --port 30335 --telemetry-url ws://telemetry.polkadot.io:1024 --light --log="sync=trace"

Charlie light node cannot sync to the newest block
