This test had been somewhat flaky. It seems to be less flaky now.
Changes include:
- Trying to not send the client->server logging RPC if the client is
about to reload due to autoupdate
- Making sure that the client doesn't send anything at all until a
little bit after starting, in order to make the ordering of messages
between tool-printed and server-printed messages more predictable
Also updated from standard-app-packages to meteor-tool.
