Address FixturesWithForeignKeyViolationsTest#test_does_not_raise_if_no_fk_violations 

Managed to reproduce CI failure at https://buildkite.com/rails/rails/builds/79496#0c03f856-9be1-4ca0-88c9-e1df21ae0a07

This commitaddresses the following errors by loading :author_addresses fixture because
`:authors` has a foreign key to `:author_addresses`.

* sqlite3 adapter
```ruby
$ bin/test test/cases/adapters/sqlite3/explain_test.rb test/cases/fixtures_test.rb -n "/^(?:SQLite3ExplainTest#(?:test_explain_with_eager_loading)|FixturesWithForeignKeyViolationsTest#(?:test_does_not_raise_if_no_fk_violations))$/" --seed 2529
Using sqlite3
Run options: -n "/^(?:SQLite3ExplainTest#(?:test_explain_with_eager_loading)|FixturesWithForeignKeyViolationsTest#(?:test_does_not_raise_if_no_fk_violations))$/" --seed 2529

* It does not reproduce with mysql2 adapter because MySQL does not have
  features to validate existing foreign keys, but added
  :author_addresses in Mysql2ExplainTest for consistency.
