version mismatch about recrypt-wasm-binding

@skeet70 suggests we just remove version from that file.

I implemented that change in #89, but it was incorrect. Thanks to @BobWall23 for spotting the logic in the automation. Automation assumes that examples/create-react-app-example/package.json depends on package.json in the root. It reads name from the root, then searches for that name in dependencies in the example app. The logic is failing because the root has no name attribute.
