[Live] Preserve file input values after render requests

Remove three lines in live_controller.js to avoid file input to be cleared after re-render. Tests ok, test in real conditions on production projects ok.

I am not certain if anyone knows the original purpose of these three lines, whether they had a specific reason for being included, or if they should indeed be removed.

As this is my first pull request, I would appreciate any feedback if I've overlooked something or can improve the process.

Thanks

There is a problem with your implementation, now files are never removed :)

For the initial reasons, I believe this thread contains most of it #834 (comment)

I'm just not sure if all what applied then still does today (data-model/name, Morphdom behaviour, etc).
