marionette: Pass params to NewWindow

The `NewWindow` Marionette command actually takes two arguments.  They
are optional, and without them, Firefox will open a new *tab* instead
of a new *window*.  Since we obviously want windows rather than tabs, so
as to place them on separate monitors, we need to explicitly specify
this when we execute the command.
