Client does not prompt to Stay on Page / Exit when Stopped

[7im-]

When the client is running, closing the tab will prompt to finish the WU, or exit.

When in the middle of a work unit, and you press the Stop Folding button to pause the client, if you then close the tab, there is no prompt to finish, or exit. It just exits.

It should prompt always.

Reported on the forum: https://foldingforum.org/viewtopic.php?f=95&t=26419 by k1wi. I confirmed it does it as well.

Remove check for fah.paused before return at https://github.com/FoldingAtHome/fah-nacl-client/blob/master/js/main.js#L1329 ?

    window.onbeforeunload = function (e) {
        if (fah.paused || typeof fah.wu == 'undefined')
            return;
        //...

It should then also check if the WU is expired. These units are so fast that they expire quickly. If it was paused 15 minutes ago there's a good chance that it WU was already reassigned. This is why I opted to allow people to easily discard this WU by pausing first. There's little cost to the science with these WU and it's best not to annoy the user.
