This commit fixes a bug caused by an invalid CSV name being generated.

`operator-sdk generate kustomize manifests` will auto-migrate a base
CSV's name to `<package name>.v<version>` if it ends in `.vX.Y.Z`.
`operator-sdk generate <bundle|packagemanifests` will always persist
base CSV metadata unless `--version` or `--from-version` are set.

internal/generate/clusterserviceversion: use an empty base if no
CSVs are in the collector
