API v2.1.0 - torrents/setCategory 409 Conflict error for new category

[zfwjs]

Please provide the following information

qBittorrent version and Operating System

qB = v4.1.3 - Ubuntu 18.04.1 LTS Server

If on linux, libtorrent and Qt version

libtorrent= 0.13.6-2build1

What is the problem

According to the API docs here:

https://github.com/qbittorrent/qBittorrent/wiki/Web-API-Documentation#set-torrent-category

the endpoint torrents/setCategory will create a new category if the category passed doesn't exist. However, passing a new category results in a 409 Client Error: Conflict. Passing an existing category is successful.

What is the expected behavior

The preference is to add a new category if the passed category doesn't exist, as stated in the API docs. **Or correct the API docs to state the category must exist prior to calling setCategory (createCategory exists and is working, so there is a work around)

Steps to reproduce

Make API call to torrents/setCategory using a new category.

@Piccirello, can you look into it?

This behavior was changed in PR #9228 and is reflected in WebAPI 2.1.0. I've updated the WebAPI docs to reflect this change. Thanks for reporting this @zfwjs.
