Make sure js/console.log output shows up in test output

[plexus]

Handle it the same way as stdout output on the Clojure side, i.e. capture it by default, and print it out when tests fail.

@kommen from some initial testing it seems you do get the output of js/console.log when running with --no-capture-output, but it's not properly printed when output capturing is on and a test fails. I'll look into that later this week or next week.

@kommen this should be fix in the latest release, let me know if this works for you!
