Directive scope "sticking" within ngRepeat (1.2.0+)

[santiago-cortes]

Directives inside an ngRepeat fail to update properly when the data model being repeated changes. See here: http://plnkr.co/s87euU5fMWeGtdtv41Qo. Does not happen in <= 1.1.5

Maybe a dup of #3909

I think the problem here is that ng-repeat is setting up the trackByIdFn to use trackByIdObjFn when it is supposed to be using trackByIdArrayFn. I think it is doing this because the first time the ngRepeatAction watch handler is called, the collection is undefined, which means that isArrayLike(collection) returns false.
