[ci skip] Adding `on_weekend?` method in edge rails guides

WIP: Errors in logs should show log tags as well.

Correct config option from only_api to api_only in test

Let t.foreign_key use the same `to_table` twice

Whenever you are sending emails in integration tests using the `:test`
delivery method you need to make sure that
`ActionMailer::Base.deliveries` is reset after every test. This piece of
boilerplate code is present in all my applications that send
emails. Let's have `ActionDispatch::IntegrationTest` reset the
deliveries automatically.

Use a URL instead of an URL everywhere

Add missing CHANGELOG for regression fix in #18155 which fixes #13387

[ci skip]

A cookie value is incorrect if value contains an escapable string in Rails 5 ActionController::TestCase

Multiple cookie values should be separated by '; ' according
to RFC 6265, section 5.4.4[1].

[1]: https://tools.ietf.org/html/rfc6265#section-5.4

The `cookies` hash isn't updated with the value generated by the output
from `to_header` so it wasn't testing anything. Rendering the cookie
value in the controller makes sure that the escaping is actually working.

Merge branch 'should-escape-cookie' of https://github.com/ma2gedev/rails into ma2gedev-should-escape-cookie

Previously if you used `t.foreign_key` twice within the same
`create_table` block using the same `to_table`, all statements except
the final one would fail silently. For example, the following code:

    def change
      create_table :flights do |t|
        t.integer :from_id, index: true, null: false
        t.integer :to_id,   index: true, null: false

        t.foreign_key :airports, column: :from_id
        t.foreign_key :airports, column: :to_id
      end
    end

Would only create one foreign key, on the column `from_id`.

This commit allows multiple foreign keys to the same table to be created
within one `create_table` block.

This is a follow-up to ea70c295 to bring back the assertion error
location information provided by minitest.

This reverts commit 0db31058.

Closes #23686.

Conflicts:
	railties/test/application/test_runner_test.rb

It's possible that the `result.location` returned by minitest is outside
the test file itself. For example in the case of mocha. This resulted in
bad rerun snipptets:

```
bin/rails test app/models/deliveries/delivery.rb:103
```

Let's always use the first line of the failed test-case in our rerun
snippet. We can display the line number of the assertion error elsewhere.
