<pre>Fix flakiness on Sierra after <a href="http://trac.webkit.org/projects/webkit/changeset/202511">r202511</a>
https://bugs.webkit.org/show_bug.cgi?id=159071

Source/WebKit2:

* NetworkProcess/cocoa/NetworkSessionCocoa.mm:
(WebKit::NetworkSession::clearCredentials):
Replacing the NSURLSessions immediately caused assertions because the tasks are not always all stopped immediately when tearing down a test.
Stopping an NSURLSession needs to be done asynchronously.  I'll try a different testing technique for <a href="http://trac.webkit.org/projects/webkit/changeset/202511">r202511</a>.

LayoutTests:
