(In [7223]) Fixes #2040: TestFile fails due to updated server certificate

Updated the certificate for base.onk.lu.se.

[Nicklas Nordborg]

Arrgh... after switching to Let's encrypt the certificate has a short lifetime. This test will most likely fail for almost every release. Don't know if we can automatically download the current certificate or use some other server. For now, I'll just make sure that a better error message is displayed instead of the unfriendly "PKIX path building failed".

(In [7280]) References #2040: TestFile fails due to updated server certificate

Added call to checkValidity() which will give a better error message in case the current certificate has expired. But there is still a problem since the server can be updated with a new certificate before the current one expires.

(In [7281]) Fixes #2040: TestFile fails due to updated server certificate

Updated to the current certificate to get rid of the immediate problem. The certificate expires April 1st so this problem will come back.
