This PR removes writes to the `github_user_id` and `github_login`
columns on the `users` table.
These writes were only being done in tests, as the production codepaths
that referenced these columns have already been removed.
Depends on https://github.com/zed-industries/cloud/pull/2743 to make the
`github_user_id` column nullable.
The corresponding database schema migration has been created in the
Cloud repo and applied to the production database.
Closes CLO-831.
Release Notes:
- N/A
This PR removes some more unused fields from the database user model:
- `github_user_created_at`
- `email_address`
- `name`
- `created_at`
These fields were not being used anywhere, and are nullable/defaulted in
the database in tests.
Release Notes:
- N/A
