Blogpost list on author page doesn't show posts where author name has different case.

[tripodsan]

Expected Behaviour

I see all the authors posts, irrespective on the case of the author.

Actual Behaviour

I see only the posts, where the case matches exactly.

Reproduce Scenario (including but not limited to)

• create a post with author name: 'Foo Bar'
• create an author with name: 'foo bar'
• on post page, click on author name -> you get to the author page
• but on the author page, the post is not listed
