Global Styles on Personal AB: Update assignment cache key

[rcrdortiz]

Proposed changes:

Since the changes are already merged, users are assigned to the control group, and the assignment is cached. With these changes, we're changing the cache key so that users get re-assigned once we merge these changes

Other information:

• Have you written new tests for your changes, if applicable?
• Have you checked the E2E test CI results, and verified that your changes do not break them?
• Have you tested your changes on WordPress.com, if applicable (if so, you'll see a generated comment below with a script to run)?

Does this pull request change what data or activity we track or use?

No

Testing instructions:

• Apply these changes
• Sandbox your API
• Go to Calypso theme showcase (logged in)
• Open the network tab and filter requests by global-styles/status
• By default you should get the corresponding assignment. Change the assignment and clear the cache and you should have the new assignment group.
