Description of change

Add tests for console.[info|error|warn].

Just copied the basic tests for log, as they're all the same thing
as log in either stdout or stderr.

LGTM. CI is green.

This section is a bit of a mess in that it's not very readable and mixes the strings and errStrings checks up. This can likely be simplified by creating a secondary array with the expected strings in the right order then just doing a for-loop through each of strings and errStrings to check each one. The code would be much easier to read and there'd be much less of it :-)

Sure, the first bunch of these can work that way since they're just testing equality. I'll do that.

For the ones doing indexOf, regex or other more complex tests, I think they're going to have to be on their own still. Some comments might be able to clarify them though.

LGTM. CI again: https://ci.nodejs.org/job/node-test-pull-request/2487/

@evanlucas looks like a single failure, for unrelated jenkinsey reasons https://ci.nodejs.org/job/node-test-commit-arm/nodes=armv8-ubuntu1404/3137/console
