Fix issues with configuration directories

- Move the old data directory if possible.
- Fix extension path to not use a hard-coded path and instead use the
  data directory.
- Create every part of the path during startup.
- Create each path when a connection is made as well in case they are
  deleted while the server is running.
- Create every part of the path before saving settings or writing a file
  using the resource endpoint.
