Fix more instances of missing remapping handling

After fixing Bug#796999, we noticed that there were
some more instances of iterators which had no associated
Dynamic object, causing them to not be updated when
the cache was remapped.

This happened in two places: In NewPackage() and in
NewProvidesAllArch().
