The PDF Viewer has a password dialog that is prompted to the user before
the document loads. However, PDF browser tests run only after the
document loads.

Alter the EnsurePDFHasLoaded() helper method to also return when the PDF
prompts the password dialog.

To do so, a 'passwordPrompted' message is sent to the PDF Viewer
embedder.
