Issue with 'isEmptyObject()'

[AdamWr]

If I'm not wrong, some scriptlets doesn't work in some cases due to issue with isEmptyObject.

Steps to reproduce:

1. Add this rule:

example.org#%#//scriptlet('set-constant', 'EventTarget.prototype.dispatchEvent', 'noopFunc')

3. Go to - https://example.org/
4. Check EventTarget.prototype.dispatchEvent in console.

It should returns noopFunc, but it doesn't work.

If I'm not wrong, it's because isEmptyObject returns true in case of EventTarget and any other object with prototype.

Scriptlets/src/helpers/object-utils.js

Line 38 in 202f6d8

export const isEmptyObject = (obj) => Object.keys(obj).length === 0;

For example:

var test = function(){};
test.prototype = { abc: function() {} };

The same happens with abort-current-inline-script, abort-on-property-read and probably with other scriptlets.
