Lang strings are not deleted properly if database deleted

[Sonya*]

There are some orphan strings in core_sys_lang_words after deleting a database (Pages):

• digest_area_cms_records<DB_ID>
• digest_area_cms_categories<DB_ID>
• content_field_<FIELD_ID>_desc
• content_field_<FIELD_ID>_validation_error

Thank you, I have created an internal bug report for this.
