 In [changeset:"39637"]:
 {{{
 #!CommitTicketReference repository="" revision="39637"
 Taxonomy: Eliminate redundant and inaccurate dupe check when creating
 categories from post.php.

 The `term_exists()` check is not needed because of existing dupe
 checks in `wp_insert_term()`. Furthermore, `term_exists()` conflates
 term names and sanitized slugs, so incorrectly marks terms like
 'C' and 'C+' as duplicates of one another.

 Props garyc40, SergeyBiryukov, kovshenin, MikeHansenMe.
 Fixes #16567.
