net.http: fail open if surrounding code does not configure TLS
Previously, if surrounding code was not configuring the TLS context
used default in net.http, it would not validate certificates at all.
This is not a security issue with prosody, because prosody updates the
context with `verify = "peer"` as well as paths to CA certificates in
util.startup.init_http_client.
Nevertheless... Let's not leave this pitfall out there in the open.
