Autosave callbacks shouldn't be `after_save` callbacks

068f092c registered autosave callbacks
as `after_save` callbacks. This caused the regression described in #17209.

Autosave callbacks should be registered as `after_update` and
`after_create` callbacks, just like before.

This is a partial revert of 068f092c.

Fixes #17209.

Also add documentation on it

This reverts commit 997f1575, reversing
changes made to f919d5f5.

ActiveJob: allow empty queue names

As discussed in #17195, Que uses blank queue names by default for
performance reasons. At the very least, ActiveJob should allow users to
choose "" as their queue name. This commit allows blank queue names, as
well as tests to make sure that nil queue names still use the default.

Invalid HTTP method will raise I18n::InvalidLocale if :en is not a valid locale.

Request#check_method would use to_sentence(locale: :en), which breaks when
I18n.available_locales does not include :en and
I18n.enforce_available_locales is true (default).

Inlined to_sentence functionality to solve this.
