Fix whitelist status evaluation of tabless network requests
Related issue: - https://github.com/uBlockOrigin/uBlock-issues/issues/651 The `behnind-the-scene` context was wrongly used to evaluate the whitelist status of the context of tabless network requests. The document origin must be used instead when it's available. Additionally, much code has been revisited for better ES6 syntax compliance.
