Because we're muppets and not using an actual ES6 Map, so default Object builtins are of course not undefined.

Used Object.create(null) instead as ES6 Maps change how you set/get from the map (functions instead) and I don't fancy updating alllll the places. Hotfixed on the matrix.org Freenode bridge.
