fix: Clarify error messages when proc-macro-srv changes working directory

Browse Source 
I'm investigating issues where users see a load of logs of the form:

```
Failed to set the current working dir to /redacted/path. Error: Os { code: 2, kind: NotFound, message: "No such file or directory" }
```

This is tricky to debug because there's two different code paths that
write exactly the same error message. Ensure they're unique.
