One time scheduled events don't have a next occurrence

check if the next[0] occurrence is defined before processing it further

Hi @bunkat , this lib is great work!
However ( :) ) I'm running into trouble when using one-off times, I think it may be related to this fix.

const later = require('later')
const sc = later.parse.recur()
  .on(new Date('2017-06-15T15:00:00Z')).fullDate().and()
  .on(new Date('2017-06-16T15:00:00Z')).fullDate()
console.log(later.schedule(sc).next(10))

yields

/home/app/backend/node_modules/later/later.js:777
        return !b || a.getTime() > b.getTime();
                       ^

TypeError: a.getTime is not a function

Comments? @faburem

That is exactly the issue I was running into. Unfortunately my pull request still hasn't been merged. I'm using my fork in production for quite a while now and didn't encounter any problems yet.

Per my work with Bree, I have an updated fork of this package called @breejs/later. See https://github.com/breejs/later if you would like to file this PR there.
