Drop user details fields from users table

What does this MR do and why?

As of !102351 (merged)

• linkedin
• twitter
• skype
• website_url
• location
• organization

are delegated to the user_details table. Before removing the ignore_columns in the User model for those fields, the actual columns need to be dropped.

rake db:migrate

How to set up and validate locally

1. Apply the migration: scripts/db_tasks db:migrate.
2. Run psql via GDK.
3. Describe the users table -- \d users -- and check that the fields above are no longer present.
