Update 8002 fails if index already exists.

This is a follow up to

In my case I had installed the restrict_ip module with the patch provided at https://www.drupal.org/project/restrict_ip/issues/3080420#comment-14862181 🐛 SQLSTATE[HY000]: General error: 1 near "-": syntax error Fixed

Which had the type_path index with the underscore in the install hook, but the update hook hadn't been included yet.

When upgrading to the latest version of the module the update hook throws an error as the index already exists.

Patch provided.
