Fix core editor root dir

[Exeloo]

core-editor

Issue description

Currently when you compile the core-editor, it calls files from core with ../core/src/...
This cause a rootDir error as the core-editor rootDir must be in the core editor.

On ts5, it's just warning or errors if using paths, but on ts6 it's a full error.
