Create and pass referred_by value to backend if p query exists in the url.

Context

We are creating a referral program to pay out rewards automatically to hunters that refer.

First create the referred_by property in the local browser.

Then when a referred hunter signs up anywhere on our site (https://community.sphinx.chat/bounties), if referred_by UUID exists in localStorage, then send it to the backend, find that person's ID, and store it on the newly created Person record as a new SQL column called referred_by.

If referred_by is already known, then the new uuid will be ignored.

This task is specifically for passing the uuid to the backend.

Acceptance Criteria

• I've tested on Chrome
• I've submitted a recording in my pr
• I've created a test that asserts that the uuid is saved in local storage if uuid is found
• I have rebased and tested locally before submitting my PR

Here is an example unit test
