[plugin-stripe] Customer is created in Stripe even if User record creation fails in Payload

Describe the Bug

When data sync between Stripe and Payload is enabled and a user record is created with an email address that's already in use, Payload throws an error, but the customer record in Stripe is created anyways. This causes orphan records in Stripe to build up.

Reproduction Steps

1. create a .env file at the root of the monorepo using the .env.example file as an example, providing a database URI and Stripe secret key. I used postgres because that's what I have access to for testing.
2. Run the test app with pnpm dev _community
3. onInit will attempt to create two users. The first API call should create a user in Payload successfully, and the second call should fail to create a user in Payload and throw an error. Then check in Stripe to see that both customer records were created.
