馃崚 kns: drop provider part of the url
supposedly in 6.7 the parsing changed a bit and now certain providerIds parse as path rather than host. the host component extraction was super questionable anyway because it means you can't get to the providerId from the url, rendering the provider part entirely pointless.
fortunately the provider part wasn't used anyway so we can simplify the url and not include the provider at all
