We can relay one header for once, in cmd-tools, the second time we trying to relay a same header which is on darwinia, will raise an error at

: telling you header exists

This will not happen

This will not happen in cmd-tools:

in static mode proof tests, cmd-tools will reset a header before we relay the new one
in dynamic mode proof tests, cmd-tools will relay header based on the bestheaderhash on darwinia
in relay service, cmd-tools will check the bestheaderhash and auto-restart when this happens
