Reference file pointing to wrong path

[Flemmli97]

For some entries you can use a resourcelocation which represents another file in the current datapack you work on. One example would be loot tables: Loot tables can contain other loottables within. For the textbox a button will appear allowing you to follow the reference. If you use a custom loottable id that you made it will error out.

1. Create any loottable and save it
2. Create a new loottable with a loottable entry using the id of 1.
3. A button will appear labelled "Follow reference"
4. Clicking on button will attempt to bring up the loottable reference only to error out. Json output will show 404.

This does NOT happen will vanilla builtin loottables
