set nfd_migrate_site to false

[geckod22]

Proposed changes

This PR aim to set the nfd_migration_site option to false once onboarding module run the first migration url step. This PR need to go with newfold-labs/wp-module-migration#158 that manage the dynamic sso onborading redirect for migration based on brand.

A customer start a Website Transfer from MFE, the option nfd_migration_site is set to true, then by sso url magic link the customer is redirected to the onboarding page for migration process. The migration module hooks on the sso success redirect and will dinamically set the url depending on the brand. Once onboarding start the migration process first step the option is set to false.
