We have not used anything related to bookmarks for PostAction
or UserAction records since 2020, bookmarks are their own thing
now. Deleting all this is just cleaning up old cruft.
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.
By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.
Previously email validations could fire when deleting posts if for
certain reasons any user validations fail on the user objects
This kind of condition could happen in core due to a corruption of a
user record, or via a plugin that introduces a new validation on User
