Fix mongoose certs

[kamilwaz]

The certificates used for MIM were broken by #4631. Erlang verifies that keyUses includes the required usage for the specific role (server/client), and this causes the ssl_certificate:verify_extkeyusage/2 function to fail.

The issue wasn't noticed immediately because the certificates are cached using a key generated by
tools/make-certs-cache-key.sh

Additionally, some SIP tests were failing on master due to an invalid configuration left behind by cets_disco_SUITE. This PR makes sure the configuration is restored at the end.
