bodhi-push's --builds flag selects all builds from the given build's release

[bowlofeggs]

It seems that the --builds flag got broken by recent changes to bodhi-push:

$ sudo -u apache bodhi-push --username bowlofeggs --builds python-rpdb-0.1.6-11.fc28

False alarm: In order to test, I had to delete existing Compose objects that came over from a production sync, and I forgot to mark the associated Update objects as unlocked, so they were just matching the query.
