Correctly read resource in build jar and dev mode (#594)

The server reference config file was only able to be read while in dev mode.
Using the build jar, the content of the file was empty, since in the build jar resources aren't actual files anymore, instead they are streams.
This caused the user config content to be replaced with an empty string.
