If sourceNamespace and targetNamespace are left blank, namespace is null inside of Git repository

[wrussell1999]

Expected Behavior

When committing to git with sourceNamespace and targetNamespace properties not set, the namespace in the flow should be the same as it was in Kestra

It sets the namespace to null
