Type: Corrupted (contains bugs)

Original PR Title: Fixed free welcome emails being sent to new paid members
Original PR Description: closes https://linear.app/ghost/issue/NY-857/free-member-welcome-email-is-sent-to-new-paid-members

Currently if free welcome emails are enabled, and a new member signs up for a paid subscription, they will receive the free welcome email in error. This is because new paid members are initially created in the free status, until the Stripe subscription is fully processed, at which point they transition to paid.

This fixes the bug by opting to skip sending the welcome email if the member has a stripeCustomer attached, which indicates that the member at least intends to become a paid member.
