[REGRESSION]: 4.8.0-4.20.7 args is not iterable error on initiation

[FossPrime]

Steps to reproduce

Run this Ultra Simplified code:
https://codesandbox.io/s/fhc-bug-shared-7otk3

Another more complete demo with the issue on 4.8+:
https://codesandbox.io/s/feathers-hooks-common-test-9e0st

Expected behavior

Should add todo's just fine on 4.8.0+, not just 4.7.0

Change that caused the regression

v4.7.0...v4.8.0

Actual behavior

• Console outputs TypeError: args is not iterable as long as 4.8.0+ is listed as a dependency.
• Importing the module is no necessary to reproduce the issue.
• @feathersjs/commons does not break the app. Indicating that we are violating a precondition.
• client side support is completely broken... tests should be added.

System configuration

Module versions:
4.8.0 - 4.20.7
4.7.0 works fine

NodeJS version: 12

Operating System: linux

Browser Version: Chrome 75

Module Loader: webpack

Getting feathers-hooks-common to run on codesandbox makes debugging real apps MUCH easier.

Looks like the issue stems from the former feathers-commons, now known as @feathersjs/commons.
feathersjs-ecosystem/commons@v1.2.0...v1.4.0

// Converters from service method arguments to hook object properties
exports.converters = {
  find (args) {
    const [ params = {} ] = args;

    return { params };
  },
  create (args) {
    const [ data, params = {} ] = args;

    return { data, params };
  },
  get: convertGetOrRemove,
  remove: convertGetOrRemove,
  update: convertUpdateOrPatch,
  patch: convertUpdateOrPatch
};

Updated the report with a simplified demo... This one depends just on memory, hooks-common and feathers, yet has the same issue.

I can't begin to reproduce this outside of code sandbox :/ It works fine on glitch. May be a babel issue.
