command: make m_property_strdup_ro with NULL mean unavailable
This catches a few cases which basically call: m_property_strdup_ro(..., ..., NULL) which would return NULL strings. This should generally be avoided (although it's allowed due to reasons), and it seems most callers actually intend this to mean M_PROPERTY_UNAVAILABLE.
