The DesktopMediaListAsh uses the AuraWindow's title as the description
for the desktop source (window or screen.) To ensure that the display's
description appears we need to set the root window's title to the
display's name. This display name matches the name shown in the display
configuration UI.

BUG=372444
TEST=In a multiple display environment trigger the picker and observe
that the displays' names are included and match those in the display
settings UI.
