Resolve an interesting case

[tunnckoCore]

When for example, there is done argument, but is not called, and there is a result which is a promise.

something like

if (isAsyncFn && !called && isPromise(syncResult)) {
  resolve(syncResult)
}

edit:

this seems to fix it

      if ((!isAsyncFn && !called) || (isAsyncFn && !called && isPromise(syncResult))) {
        resolve(syncResult);
      }

i think we should handle this case, in that way. It is a lot better to auto-magically do it, instead of returning rejected promise that signals the user that he didn't called the done callback argument.

examples

var promisify = require('redolent')

var fn = promisify(function (app, done) {
  if (app.aaa === 1) {
    done(null, 111)
    return
  }
  return Promise.resolve(123 + app.aaa)
})

fn({ aaa: 2 }).then(console.log) // => 125
// or
fn({ aaa: 1 }).then(console.log) // => 111

both work
