<pre>REGRESSION: Crash when typing into text field that clears itself on iOS
<https://bugs.webkit.org/show_bug.cgi?id=135044>
<rdar://problem/17640443>
Reviewed by Darin Adler.
* WebProcess/WebPage/ios/WebPageIOS.mm:
(WebKit::WebPage::requestAutocorrectionData):
wordRangeFromPosition() returns null in some cases; null check range
before dereferencing it. Moved some variable declarations around to
better match our style.</pre>
