Https://solid.community:8443 - test server

from @michielbdejong I updated (almost) all the dependencies of NSS. The number of vulnerabilities reported by npm audit is finally back at 0 (down from 528). @bourgeoa can you update https://solid.community:8443/ for testing v5.4.2? Let me know if you find any bugs (I fixed all the ones I could find, but there may be more).

It’s a wonderful work.

The test-server https://solid.community:8443 has been updated to v5.4.2
We shall keep it running a few days before porting to https://solid.community (which runs v5.4.0)
Please test and report new issues.
