Assertion failure in PluginStream::~PluginStream when running userscripts/user-script-plugin-document.html

[Adam Roben (:aroben)]

To reproduce:

1. run-webkit-tests userscripts http

You'll hit an assertion in PluginStream::~PluginStream. (run-webkit-tests will blame http/tests/cache/stopped-revalidation.html, but that test doesn't cause a problem on its own.) Here's the failing assertion:

    ASSERT(m_streamState != StreamStarted);

See the URL for the backtrace.

I've added this test to the Skipped file.
