Support phx-trigger-action

I'm not sure if this is something that can be supported but it doesn't appear to work at the moment.

I've got a form in a live view that submits to a controller when phx-trigger-action resolves to true, as explained here. This pattern lets you use liveview for realtime form validation, then submit the form to a controller where controller stuff needs to happen (interacting with the conn). Currently the form is not submitted when triggered using phoenix_test.

It seems like something that would fit right in to the phoenix_test wheelhouse, testing an interaction between liveviews and controllers.

Thanks for opening this issue (and the PR) @totaltrash! I think this would be a great addition to PhoenixTest.
