Summary: This `break` statement causes `./bin/hunks migrate` to only migrate one-hunk-at-a-time, which is unnecessary and slightly misleading. Instead, allow the script to migrate //all// legacy hunks to modern storage. In particular, this means that we can recommend that installs run this command sometime before D13222 is landed.
Test Plan: It's a pain to setup the data necessary to test this, but this is identical to the change that I made on our production install when I migrated our hunk storage.
