Public bug reported:
Most of the methods that increase the generation for a resource provider
also update the value of `generation` in the object that calls it, but
there is one place where it was missing: the _set_allocations() method
of the AllocationList class. This resulted in some ResourceProvider
references having stale values for `generation`, which would cause a
ConcurrentUpdateDetected exception to be raised.
