Oops, sorry about that. I didn't realize until now that 'ert-info' 
computes its message immediately, rather than at the time of printing 
the info.[1] I've added a bit of code to ert.el to support this case, 
which will hopefully produce better output.

I also added the server.el logs to the output of test failures. Note 
that they'll print the environment variables of the client, so it's 
probably worth skimming over them before posting just in case there are 
any secrets in there.

[1] Maybe there's a better way to do this, but it should at least work 
for the time being. I'm open to alternatives here so that these tests 
are as informative as possible when they fail.
