Comments: Update comment cache in the upgrade routine for changing the `comment_type` DB field value in comments table. 

This ensures that comment object cache is cleared after changing the comment type to `comment` instead of an empty string.

Add a unit test for `_wp_batch_update_comment_type()`.

Follow-up to [47597], [47626], [48225], [48227].

Props imath, westonruter.
Fixes #49236.
