Category URL rewrites not generated after changes to "catalog/seo/category_url_suffix", "catalog/seo/product_url_suffix" or "catalog/seo/product_use_categories"

[simonworkhouse]

When updating the values of "catalog/seo/category_url_suffix", "catalog/seo/product_url_suffix" or "catalog/seo/product_use_categories" the entries in the url_rewrite table aren't generated except when a categories url_key is updated.
There doesn't appear to be any mechanism to re-generate these URL rewrites when these configuration values change.

Preconditions

1. Magento 2.2.5
2. PHP 7.1.20
3. MySQL 5.7.23

Steps to reproduce

1. composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition {install dir}
2. cd {install dir}
3. ./bin/magento setup:install --backend-frontname=? --db-host=? --db-name=? --db-user=? --db-password=? --base-url=? --admin-user=? --admin-password=? --admin-email=? --admin-firstname=? --admin-lastname=?
4. ./bin/magento sampledata:deploy
5. ./bin/magento setup:upgrade
6. Edir database table "core_config_data" - update the values for "catalog/seo/product_url_suffix" and "catalog/seo/category_url_suffix" to ".php", the value for "catalog/seo/product_use_categories" to "1" and run "./bin/magento indexer:reindex"

Expected result

URL rewrites to be generated in the url_rewrite table and the URLs on the frontend should match the new suffixes and format.

Actual result

No URL rewrites are generated and the frontend still displays the old URL format and suffixes.
