Properly print 'None' for option types from FSI [6690744]

FSI output properly handles 'Some x', but often prints 'None' as 'null', apparently when the value is part of a larger type.

let x : uint16 option = None

correctly results in:

val x : uint16 option = None

while

let y : string * uint16 option = "", None

instead prints:

val y : string * uint16 option = ("", null)

This should certainly be fixed, as much as possible
