List replace with deferreds does not take into account stale/overtaken deferreds #2136

When updating a list through the can.List.prototype.replace method and deferreds, the replace method fails to check whether the settled deferred is not stale, i.e., overtaken by a later replace operation on the same list.

When deferreds settle out-of-order (as is common with server requests and network connections over which the author has no control) this leads to potentially unexpected or invalid application states.
