When a keying set is enabled and the keying set option "Active Keying Set" was chosen from the menu, it would give an error. That is because the active keyingset uses a special ID string (`"__ACTIVE__"`) that doesn't actually exist as a keying set. To fix it, explicitly check against that string and return the active if encountered. Pull Request: https://projects.blender.org/blender/blender/pulls/116192
