Peter reported a test failure on FreeBSD with the new reconnect test:

ERROR:tests/test-char.c:353:char_socket_test_common: assertion failed:
(object_property_get_bool(OBJECT(chr_client), "connected",
&error_abort))

It turns out that the socket test code checks both server and client
connection states, but doesn't wait for both.

Wait for the client side as well.
