test: fix flake in GoAwayThenClose (#3052)

Browse Source 
In the event of a race, the first server may not be fully serving before the
client attempt to connect, then the second server may attempt to field the
FullDuplexCall, which it does not implement.

Fix the race by giving the client only the first server's address until after
the FullDuplexCall is started.
