[FIX] config: Feed dedicated tsconfig.json file to jest

Since 457fe70, we changed stopped compiling the `.ts` files in the
`tests` folders to save compilation time. Unfortunately, jest was using
the very same file to compile (via `ts-jest`) and it actually needs to
compile `tests/setup/jest.setup.ts` to work properly.

This commit introduces a new dedicated `tsconfig` file for ts-jest in
order to retain the improvements of 457fe70.

closes #1317
