Message:

DirectDownload: fix #21935 and #21952

#21935: "Error fetching URL" when trying to download a GPS track

This was caused due to a change in where OSM stores GPX data files.
OSM now uses s3 buckets, and redirects using a signed URL. S3 does
not like multiple authentication methods.

#21952: Only the first tag in the Tags column in "Download Track" window is shown

This was caused due to only keeping the last encountered tag.
