[Bug] MusicBrainz alias overriding artist name even with KOITO_DISABLE_MUSICBRAINZ set to true

[adamantmarble]

Describe the bug
I think what's happening is that if an artist name is an alias for another artist on MusicBrainz then Koito will replace the artist I have in metadata which is submitted to Koito by Multi-Scrobbler. I have KOITO_DISABLE_MUSICBRAINZ set to true but it still does this.

An example I keep having to edit is with the artist "Volant" who changed to "nuphory" but still has a lot of music under the old name that I listen to.

Here is the MB page: https://musicbrainz.org/artist/41656317-c512-456f-9fe7-1f7fb8482a34/aliases

Thanks for any assistance!

To Reproduce
Steps to reproduce the behavior:

1. Set KOITO_DISABLE_MUSICBRAINZ to true
2. Send a scrobble with just an artist that is an alias of another artist
3. See it scrobble to the other artist MusicBrainz has it as an alias for

Expected behavior
If KOITO_DISABLE_MUSICBRAINZ is set to true then the artist sent by the scrobbler should not be overwritten by the MusicBrainz alias.
