Fix bug in H2 test data & expectations broken by latest Node

This was our bug, but was hidden by Node's SNI handling. That got
tightened in a fix recently, and this started failing. It included the
port in the SNI, which should never happen. With this change it's more
representative of real traffic (ish, it's still a broken edge case) and
should hopefully pass everywhere.
