SwipeRefreshLayout.setOnRefreshListener should force update

on `todo-mvp-kotlin` and `todo-mvp-rxjava` the TasksFragment's `SwipeRefreshLayout.setOnRefreshListener` call always has ` { presenter.loadTasks(forceUpdate = false) }`

I'm wondering if I'm misunderstanding the code but wouldn't you expect a "pull to refresh" action to query the network?

Inspect TasksFragment in the todo-mvp-kotlin and todo-mvp-rxjava samples, starting at each SwipeRefreshLayout.setOnRefreshListener call. Verify how the listener passes forceUpdate to presenter.loadTasks and confirm that pull-to-refresh performs the intended network refresh in both samples.
