[see #18392]

Correct route requirements by overriding defaultls

Add a test-case to make sure that `create_table` with
a `foreign_key: true` and an adapter without foreign key support
does not blow up.

Motivated by #19794.

Originating from: https://github.com/rails/rails/commit/99a6f9e60ea55924b44f894a16f8de0162cf2702#commitcomment-10855210

This reverts commit 08ff4ccb, reversing
changes made to 6c9ed6db.

Caused by #17920.

Closes #19545.

This patch introduced regressions because initializers were no longer
loaded. Specifically missing inflections result in broken restores of
the database.

Also added reference for to_date, as it belongs historically.

sprockets-rails will only add `Rails.application.assets` if compile is
no false. See change on sprockets-rails
https://github.com/rails/sprockets-rails/commit/d7c7ee19991c565eb77ee143be2d009ba4472122

See the behaviour change on sprockets-rails
https://github.com/rails/sprockets-rails/commit/56725e5843662189c6701478f7598db306d5fb02

We need to ignore the `assets_prefix` when running a command like `rake
routes`. However we cannot reference asserts_prefix from action_pack as
that is a sprockets-rails concern.
See this is now implemented on sprockets-rails
https://github.com/rails/sprockets-rails/commit/85b89c44ad40af3056899808475e6e4bf65c1f5a
