Scott Taylor eadc17c4f9 In wp_insert_term(), when no slug is provided, check for an existing term by name. If it exists, use that slug instead of calling sanitize_title( $name ).
Prevents creating an endless number of terms like `A+` or `$$$$` in any given taxonomy.

Props wonderboymusic, SergeyBiryukov, aaroncampbell.
Fixes #17689.
