Bug: allowed projects is set to 1 for customer moving from trial to paid

[matthewelwell]

This needs confirmation but we had a customer that had only 1 allowed project after moving from trial to paid SaaS.

To resolve this, I manually updated the value of allowed_projects in their OrganisationSubscriptionInformationCache record in the database from 1 -> null.

We need to verify the logic here and investigate.
