"Loop Metadata URLs from Service Metadata" failing although prerequisite is validating

[JohannaOtt]

• a description of the steps to reproduce your issue: When validating this WFS in the staging version of the validator (production is currently running into an error for WFS), the test with id "EID3c74fa68-1478-4a04-9b0e-72e8ca3a8aa7" is failing. Attached to the test are two messages of which one is saying: "java.lang.Exception: Test step "Get Metadata from Service Metadata" failed!". But the mentioned teststep did not fail: Not sure if that message is leading to the test failling but as there is no detailed error message, it is hard to assess the reason for the validation error.
