Sending from Lotus Lite results in 0 nonce

[Kubuxu]

Describe the bug
When sending a message from Lotus Lite node the nonce is always set to 0.

Version (run lotus version):
Local:

Daemon:  1.7.0-dev+mainnet+git.8a19ddbb9+api1.1.0
Local: lotus version 1.7.0-dev+mainnet+git.8a19ddbb9

Remote:

Daemon:  1.7.0-dev+mainnet+git.8a19ddbb9+api1.1.0
Local: lotus version 1.7.0-dev+mainnet+git.8a19ddbb9

To Reproduce
Steps to reproduce the behaviour:

1. Start lotus lite node.
2. Send two messages, second will fail with:
   ERROR: executing send: mpool push: failed to push message: minimum expected nonce is 6: message nonce too low

Expected behaviour
Message sending works.

It works when you are using one node, but the nonce is not correctly tracked between different nodes.
