Check what happens when well-known documents change

[m-mohr]

I just ran npm run crawl, but there's an issue. At least it did not show the recently added 1.0.0 EURAC back-end and removed 0.4.2, I did not check the other back-ends.

EURAC well-known document had 0.4.2 listed only. Now it has only 1.0.0 listed. After crawling still only 0.4.2 was available and it said 0.4.2 was not available for several days.

Running npm run drop -- --yesimsure and then crawling again solved the issue.

To me this sounds like something going wrong when links in the well-known documents change (the base URL is part of some database indices etc.) -- needs further investigation.
