<pre>Prevent crash when attempting to copy an image
https://bugs.webkit.org/show_bug.cgi?id=159288
<rdar://problem/23507828>
Reviewed by Brady Eidson.
WebKit could crash if the HTMLImageElement had a null cachedImage member.
A little investigation showed that the URL we retrieve from the cachedImage
is never used, so rather than adding a null check, let's just pass a
default argument. The actual URL gets read from elsewhere in the pasteboard
processing code.
* WebProcess/WebPage/ios/WebPageIOS.mm:
(WebKit::WebPage::performActionOnElement): Don't bother passing the
unused URL argument to the pasteboard method.</pre>
