Prevent crash on export for obj with no material (#1903)

Browse Source 
During export material_checksum was always checked against a stringed
list `'[]'` for an empty material while default value
for material_checksum default was `''`. So it was trying to update
material of object which have none (eg. IfcRelSpaceBoundary).
