Maybe pollTaskFor should wait()? about ember-lifeline

[scalvert]

Hmmm, I wonder if we need to return settled() in that function.

export function pollTaskFor(token) {
  assert(
    `You cannot advance pollTask '${token}' when \`next\` has not been called.`,
    !!queuedPollTasks[token]
  );

  run.join(null, queuedPollTasks[token]);

  return settled();
}

It'd be a bit weird to import test helpers stuff into prod code, but such is life when you expose testing functionality in a module.

@rwjblue - thoughts?

Seems "fine"ish...

Unconvincing response...
