Feature: allow "submit form" component to work with flows that have a single input

[waynehamadi]

When connecting a form to a flow that doesn't have any inputs, nothing happens.

I was expecting to just have a button to submit and trigger the flow?

I just found out that the "button" component works with this flow.
Still, I think what I am asking is a minor change and will avoid confusion from Bluewind contributors, this way we can always just use the submit form component
