There are several situations in which it is a valid system state for
Keys to PollMessages on Domains to point to entities that don't exist,
chief amongst them when a domain has been soft-deleted. We also can't
simply null this out when soft-deleting domains, because there may be
an un-acked recurrence meaning it can't be deleted.
Given this, it doesn't make sense to check for entity existence here,
as it is not a system invariant and cannot easily be made to be so.

The dark lord Gosling designed the Java package naming system so that
ownership flows from the DNS system. Since we own the domain name
registry.google, it seems only appropriate that we should use
google.registry as our package name.
This change renames directories in preparation for the great package
rename. The repository is now in a broken state because the code
itself hasn't been updated. However this should ensure that git
correctly preserves history for each file.
