Legacy audioscrobbler broken for scrobbles from mpdscribble

At least since v3.2.3 is when I noticed (it used to work with no other changes). Confirmed issue is also present on latest. I've pulled a few logs.

Config for mpdscribble is simple:

[last.fm]
url = https://scrobbles.home.lan/apis/audioscrobbler_legacy/
username = doesntmatter
password = <api_key_here>
# The file where mpdscribble should store its Last.fm journal in case
# you do not have a connection to the Last.fm server.
journal = /home/alex/.cache/mpd/mpdscribble-maloja.journal

Navidrome scrobbles just fine through listenbrainz endpoint, so I suspect this is likely a recent regression.
