Add p-one module

This is a good idea. I've sometimes wanted to be able to do a test in p-any to make sure the value is valid before returning. You're not really taking advantage of concurrency here, which is the point of these modules existing, otherwise you could simply use Promise.all(), like I commented in the other issue. This one has potential though, as you could return the moment the first resolved promise passes a test. I do wonder if it would make more sense to instead add a validation/testing argument to p-some and p-any instead. Thoughts?

Fixed now.

That might be a good idea. How would that work though? Would it return false if the test fails and the resolved value if it succeeds?

This is what I was thinking: sindresorhus/p-some#1
