Please give us a description of what happened

If Yoast SEO metabox is disabled, then Yoast SEO sidebar doesn't save the metadata like SEO title, meta description. Also, this data does not appear in the page source and remains missing from the post overview page as well.

This issue with saving data applies not only to the SEO title/description but also to all our settings added via the sidebar.

To Reproduce

Step-by-step reproduction instructions

1. Disable Yoast SEO metabox from post editor > Preference > General > Advanced and disable the Yoast SEO toggle button.
2. Add a new post, use the Search Appearance tab of Yoast SEO sidebar to add the meta description [for example]
3. Publish the post. Refresh the page and open the Search Appearance tab of Yoast SEO sidebar.

Expected results

1. The data added via Yoast SEO sidebar should remain saved without metabox being enabled.

Actual results

1. Metadata is not being saved in the Yoast SEO sidebar
