Use a proper condition check when dealing with flag vectors

Browse Source 
When reading flag vectors, non-existent vectors are being translated
to [] (empty list). When writing them, the flag condition was
strictly checking for None and an empty list [] would result in an
empty vector being serialized, which should not happen.
Related to #871.
