Return future when running a command

This should fix #415

It looks like CI is failing because of linting errors on a file I didn't touch

The reason converting this Future to a Promise fixes this bug is because it forces the Future to eagerly evaluate. The Neutrino API's run method is designed to allow the returning of Futures from the result of running a command, so there must be something else going on here.

Walking through the code, it appears that invoking the command function doesn't actually return anything. So instead of making the change you have here, could you modify packages/neutrino/bin/base.js line 20, to return the value of running the command function? That should indeed fix this problem for all commands.

@eliperelman yup, you were exactly right. I just updated the PR

Looks great, thank you!
