Fix renaming

There are a few issues with the current renaming support.

- When doing the initial synchronization there is overlaps with names. PuLP and pulp used to both be allowed, but pulp was renamed to pgpulp.
- When a rename occurs PyPI updates the journal.name entries to the new name. This will cause creation to occur before the rename takes place if we see any action via the name name before we see the rename entry (100% chance of this on initial syntonization).
