Improve logging in scriptlets — save reference to console

Currently if website overrides `console.log` or other properties then logging does not work.

Steps to reproduce:
1. Add to user rules:
```adblock
example.org#%#//scriptlet('prevent-setTimeout')
example.org#%#//scriptlet('log-on-stack-trace', 'document.querySelectorAll')
```
2. Go to - https://example.org/
3. Run in console:
```js
const noopFunc = ()=>{};
console.log = console.table = noopFunc;
setTimeout(()=>{const ads = {};});
const adblock = ()=>{ document.querySelectorAll('p'); };
adblock();
```

Scriptlets should log information to console.
There is nothing in console because `console.log` and `console.table` have been overridden.

It works fine if `console.log = console.table = noopFunc;` is commented out.
