Bad error message `error bootstrapping chunk journal: journal index is malformed` when a new client connects to an older version of the server

I have a long running server process to process the wikipedia import. I build `dolt` from main every day or so. I use the `dolt` CLI to connect to the server, make commits, push and gc. If the dolt used for the client gets too far ahead of the dolt used for the server, I get the following scary error message:

```
$ dolt push
Failed to load database.
error bootstrapping chunk journal: journal index is malformed
$ dolt gc
Failed to load database.
error bootstrapping chunk journal: journal index is malformed
$ dolt commit -am "3,063,000 pages imported"
error: Failed to commit changes.
```

The fix is to stop the server and start it again as the error is a symptom of the client being too far ahead of the server.

We should make the error message less scary and suggest the user restarts their server with the latest Dolt.
