HTTP2 bug fix

[BatMiles]

What does this PR do?

• fixes the HTTP2 crash we were seeing on some second page scans
• fixes the session recording test
• uses URL built-in instead of deprecated library function
• removes some unused util functions and collector variables
• refactors a number of files into a new subfolder
• creates a new hasOwnProperty helper function
• various minor improvements: function renaming, removing commented-out logs, whitespace, etc

Why are we doing this? How does it help us?

Crashes are bad

How/where should this be tested?

On it's own and in conjunction with the lambda

What are potential areas for future improvement? Are there any dependencies (especially on 3rd party code)?

There's plenty more refactoring to do, but I figured this PR was getting large enough

What are the relevant tickets, tasks, or documents?

This is much more readable, thank you. My first impression of this is the same: links gets set to dedupedLinkArray filtered for links that also exist in the original input array. Seems like an unnecessary check since dedupedLinkArray is already derived from links_with_duplicates.

This is great, I'm so glad that you discovered the (cookie) cache clearing trick!
