Vadim Zeitlin 2ef44570fd Work around bug with out of order JS execution results
Modify the sample to show the correct value of the user agent when using
WebKit backend as this got broken by calling it inside an event handler
executed later but before the idle event handler could dispatch the
result of JS executed from inside WebKit AddScriptMessageHandler()
implementation, resulting in misinterpreting this result ("{}") as the
user agent string.

The real fix is, of course, to deal with the JS execution results coming
out of order in some way.
