Fix and re-enable TCPSocketTest.ServerReceivesMultipleAccept

This test is flaky because the test closes client connection during each
for-loop iteration. When server checks whether the connection is still connected
using accepted_socket_->GetPeerAddress() in
network::TCPServerSocket::OnAcceptCompleted(), it will get
net::ERR_SOCKET_NOT_CONNECTED (-15).

This test keeps the client sockets alive and delay disconnecting them until
server finishes all Accept() callbacks.
