tfjs hermes bug

For issues:

• tensorflow/tfjs#5972
• tensorflow/tfjs#6526
• tensorflow/tfjs#7056

Reproduction

• Install dependencies with yarn (it is not necessary to setup tfjs git submodule)
• Run npm run tfjs:node
  • Runs tfjs code with Node.js
  • Prints "result 2" without error
• Run npm run tfjs:buildrun
  • Bundles tfjs code with Metro
  • Runs tfjs code with Hermes
  • Gives the error "Uncaught Error: Argument 'x' passed to 'argMax' must be a Tensor or TensorLike, but got 'e'"

We can probably get more readable build output by tweaking the metro config.
