Error when emails is undefined

Occasional error in CircleCI:

Cannot read property 'html' of undefined

@Stojdza I saw this recently, would it be something to do with promises in the email client? Any ideas about how we'd fix this, or workaround it?

I think I know the reason. The issue comes from #pollEmailsByRecipient and its validator. The current validator allows exiting polling on the first try. Replacing validator with something like this: emails => emails.length > 0 should potentially fix this issue.

This should be fixed by #1223
