JavaScript exception being swallowed?

[bhelx]

As of v1.3.0, when the js code throws an exception it seems to be getting swallowed by some top-level trap:

$ cat examples/exception/script.js

function greet() {
  throw new Error("I am a JS exception")
}
module.exports = { greet };

$ extism call examples/exception.wasm greet --input="Hello" --wasi
Error: Exception generated by QuickJS
returned non-zero exit code: 4294967295

This exit code a bit bizarre also. I suspect this might be related to the rquickjs refactor but not sure. When we do figure it out we need to add a test for this.

I think i found where the exception is originating from at least:

https://github.com/DelSkayn/rquickjs/blob/6d8f612636c1a6d4b4acd7a78ce30063666a1b78/core/src/result.rs#L530

Maybe we need to refactor the error handling code.
