MSD Billing: Modify removal flow for one-time purchases

[chrismccluskey]

Fixes SHILL-1404

Proposed Changes

• Hide the error notice shown when one-time purchases cannot be cancelled.

Why are these changes being made?

• Currently if a one-time purchase cancellation is attempted by visiting the URL directly it will redirect the customer to the purchase management page with an error message saying that the purchase has already been removed. This isn't true - the purchase is still active.

Testing Instructions

• Add a quick start session via SA
• Checkout the mccluskeyc/shill-1404 branch to your sandbox
• Try to cancel that purchase in the multisite dashboard. From /v2/me/billing/purchases click "Manage Purchase" then append /cancel to the end of the URL.
• You should be redirected back to the same page you were on, but with no error message.

Pre-merge Checklist

• Has the general commit checklist been followed? (PCYsg-hS-p2)
• Have you written new tests for your changes?
• Have you tested the feature in Simple (P9HQHe-k8-p2), Atomic (P9HQHe-jW-p2), and self-hosted Jetpack sites (PCYsg-g6b-p2)?
• Have you checked for TypeScript, React or other console errors?
• Have you tested accessibility for your changes? Ensure the feature remains usable with various user agents (e.g., browsers), interfaces (e.g., keyboard navigation), and assistive technologies (e.g., screen readers) (PCYsg-S3g-p2).
• Have you used memoizing on expensive computations? More info in Memoizing with create-selector and Using memoizing selectors and Our Approach to Data
• Have we added the "[Status] String Freeze" label as soon as any new strings were ready for translation (p4TIVU-5Jq-p2)?
  • For UI changes, have we tested the change in various languages (for example, ES, PT, FR, or DE)? The length of text and words vary significantly between languages.
• For changes affecting Jetpack: Have we added the "[Status] Needs Privacy Updates" label if this pull request changes what data or activity we track or use (p4TIVU-aUh-p2)?
