[FAL-960] Copy static overrides to instance on creation

Copy draft static overrides when provisioning a new betatest instance.

We were already copying other configuration from the betatest app, but forgot about static overrides. Copying everything ensures that the UI doesn't show any pending changes while the first appserver is being provisioned.

Ticket: FAL-960

Test instructions:

1. Register a new account on Ocim stage and validate your email.
2. Your instance should start being provisioned.
3. Verify that the deployment toolbar says "Publishing" and that there are no pending changes.
4. Make some changes to your instance configuration.
5. Verify that the deployment toolbar now shows the number of pending changes.
