[heycam/webidl] Fix "react to a promise"'s default handlers (#922)

"React to a promise"'s default handlers used to return undefined rather than propagating the resolved value or the rejection reason to the returned promise. This change fixes that, and changes "upon fulfillment" and "upon rejection" to return the resulting promise.

Closes #921.
