Fix chrome frame net tests which started crashing on startup after revision 78037 which adds a ContentBrowserClient interface which serves as a delegate to the content code.
Fix chrome frame net tests which started crashing on startup after revision 78037 which
adds a ContentBrowserClient interface which serves as a delegate to the content code.

Fix is to initialize the ContentBrowserClient interface as part of the initial bootstapping
code in the chrome frame net tests suite.

BUG=none
TEST=chrome frame net tests should run to completion.
