Improve tag matching logic for Bilibili connector

[turbodog03]

Describe the changes you made
If there is an exact match between a tag and a possible Artist/Track, it should be used as the Artist/Track.

For example:
when detected these possible artist and tags:

Video Title:【Official Music Video】輪符雨（Refrain）/ MyGO!!!!!【原创歌曲】
PossibleArtist: Official Music Video,MyGO_AveMujica,MyGO!!!!!
FilteredTags: MyGO!!!!!,mygo

Obviously, MyGO!!!!! is the artist name, and there is a tag that exactly matches it. But there's also a tag named mygo. According to the previous logic, mygo could be recognized as artist, instead of the obvious correct answer(which is confusing)
