Title: GC, parent call and js.get

js.get always return the same table if the same js object/function is referenced
garbage collection work, so when a js.get'ed variable is collected in lua, the corresponding thing in the Lua.wrappers table will be freed too
parent object is tracked to make calls with a correct "this"
