Media views: consider to remove the refresh-attachment link

[afercia]

Related: #26550

The refresh-attachment link in /wp-includes/media-template.php seems to be unused since r27445. See in the screenshot below how it worked in WordPress 3.8

Now that the image editor has been brought into the media modal I don't see any reason to keep this link, unless I'm missing something.

I'd propose to simply remove it together with the related JavaScript and CSS. Patch welcome :)

Does this link actually appear anymore? I hadn't realized it was still in the code because I haven't seen it in so long. Let's definitely get rid of it, anyway.

Refresh attachment links in the media modal are unneeded since bringing the image editor into it in [27445].

Props rommelxcastro.
