[Feature]: Always display warning on neurodata object construction if required properties are missing

[ehennestad]

What would you like to see added to MatNWB?

At the moment, a warning is displayed when an object is created without required properties, but only if the object is displayed, not when the object display is suppressed by a semicolon (see example below).

This should be improved so that the warning is always shown:

  IntracellularElectrode with properties:

                  description: ''
                       device: []
                      cell_id: ''
                    filtering: ''
    initial_access_resistance: ''
                     location: ''
                   resistance: ''
                         seal: ''
                        slice: ''

Warning: The following required properties are missing for instance for type "types.core.IntracellularElectrode":
