Fix textual summary duplication bug

[GilbertCherrie]

Fixes: #9218

There is an issue where the textual summary page is being duplicated. This is due to the code:

  if (props.options) {
    document.addEventListener('DOMContentLoaded', () => {
      ReactDOM.render(component, document.body.appendChild(document.createElement('div')));
    });
  }

This code is used to generate the print summary screen.

The issue is that currently if (props.options) is true but props.options is an empty object. So instead of just checking if the object exists we can also check if it contains any data by looking at the length of the keys array. This prevents the textual summary from being duplicated.

Before:
In the page elements we see an extra div being rendered at the bottom between the error-modal component and toast-wrapper div.

After:
This div is no longer being rendered in the page elements.

Also, the print summary screen is left unchanged by this pr.
