test(fixtures): update rest-props-multiple to repro #138

To reliably repro the bug in #138, update the rest-props-multiple example.

This can occur when using an intersection and also have a prop name that incorrectly extends the restProps.

$ bun --bun tsc --project tsconfig.fixtures.json

This expectedly failed. Rebased #138 on this.
