Unhandled error when initializing client for unknown user

Consider Unleash/unleash-client-node#35 and corresponding PR Unleash/unleash-client-node#36

I encountered this when trying to run ember build -prod within an openshift container.

Would it be an option to reverse the order here https://github.com/stefanpenner/username-sync/blob/master/index.js#L7 so it would be possible to set ENV to avoid a call to os?

Strike this, this doesn't sound terrible performant. Maybe a try ... catch is better

We're also running into this when trying to run this with ember inside a docker container. I made a small change, mostly taken from here:

sindresorhus/username@ad9043f

I'm going to submit a PR so this can be available to others (and to make sure I haven't done something stupid as I'm not a javascript guy), but in the meantime, we will use our own version.
