Fix 'xml-prune' — logging, new Request()

[AdamWr]

• Fix issue with logging
• Fix issue with not pruning if new Request is used

---

Currently if type of request is not a text then there are errors and script might not work correctly.
Steps to reproduce:

1. Add this rule:

example.org#%#//scriptlet('xml-prune')

2. Go to - https://example.org/
3. Run in console:

(() => {
  const xhr = new XMLHttpRequest();
  xhr.open('GET', '/');
  xhr.responseType = 'blob';
  xhr.onload = () => {
    console.log('test');
  };
  xhr.send();
})();

There is an error - Uncaught TypeError: text.trim is not a function

Another issue is that, if Request constructor is used in fetch then request is not pruned/checked.

(async () => {
  const request = new Request('/');
  const fetchContent = await fetch(request);
  const text = await fetchContent.text();
//...
})();
