 Priority:  normal          |  Milestone:  7.2.1
Component:  Temporal        |    Version:  7.2.0

----------------------------+-------------------------
 When trying to register a list of VectorDataset objects in a STVDS
 using register_map_object_list(delete_empty=True), it ends up with the
 following error:

 {{{
   File "/usr/lib/grass72/etc/python/grass/temporal/register.py", line
 480, in register_map_object_list
     if map_layer.metadata.get_min() is None and \
 AttributeError: 'VectorMetadata' object has no attribute 'get_min'
 }}}

 A minimum working example is attached.
