Hi,

in https://musicbrainz.org/edit/54240176 accridEYE noticed that I added a duplicate by mistake. The URL cleanup for Songkick didn't notice that the URL without the artist name was already there.

URL that was already added to this artist:
https://www.songkick.com/artists/3909026

URL that I added to this artist:
https://www.songkick.com/artists/3909026-courtney-barnett

Have a nice day,
yeeeargh

Solution is to standardize Songkick URLs so as to avoid duplicates:

• Protocol is (already was) set to https
• Domain name is set to www.songkick.com
• Slugs are removed, for example:
  https://www.songkick.com/artists/3909026-courtney-barnett
  will be replaced with
  https://www.songkick.com/artists/3909026
  (Note that Songkick automatically appends slug if missing.)
• Unneeded trailing subpaths (e.g. /calendar}), queries (e.g. ?source_product=skweb), and fragments (e.g. #calendar-summary) are removed too.
