test: mocha bump

This sounds like the tests don't terminate. Later version of mocha removed the "exit once all tests finished" behavior (or moved it behind the --exit flag). A common fix is to make sure that we close all servers etc. in after blocks so the process exits naturally.

Another quick fix is to just add --exit to test/mocha.opts.

@jkrems yep, I already added it in package.json, do you think mocha.opts is more appropriate?

Yes, we always want these kinds of changes in mocha.opts. Putting them into package.json removes the ability to simple run mocha test/file.test.js (or at least makes it behave differently). :)
