[BUG] Endless redownload and unpack txhashset archive

[johanneshahn]

After starting a node which was about 1 week offline the sync process is updating fine.
It syncs the headers and start downloading the txhashset archive and updates to the latest block.
The Message "Node synchronised" is shown. All fine here.

But after this, the Debug log shows additional txhashset archive download progress.
It unpacks the tx hash archive, validates all fine and then it start to download the txhashset archive from peer again.
It never stops.

To Reproduce
Sync the node to latest height. Stop Node and let it shutdown for some days to reach the txhashset archive download progress.
Start the node again to sync to latest block. Wait for node to be synchronised (Log: Node synchronized ...).
Watch the log "DEBUG" for Message handle_payload: txhashset archive: xxxxx/xxxxx.
