Outcome printer incoherence with conjunctive types

[Octachron]

When printing conjunctive types, like

type t = pri [< `X &(int) &(float)];

the outcome printer outputs:

type t = pri [< `X &(int & float)];

which cannot be parsed back by reason parser.

(Note that conjunctive types are mostly a type-checking artefact, an they are not really intended to be used directly, so the incoherence is quite minor.)
