This is an indirect way to tell presentation_receiver.html to close its
connection, and this message isn't understood by the test mrp, IIRC. I would at
least extract this into its own function (initiateCloseFromReceiverPage).
Another way would be to locate the WebContents hosting the receiver page in the
browser test and execute a JS script to close connection.

Done.
