System Information
Operating system: Debian GNU/Linux 10 (buster)
Graphics card: NA

Blender Version
Broken: 2.80, 2.81 (since)
Worked: 2.79

Short description of error

When calling this function in a python script and the the context's space_data is None, an "AttributeError" is raised.

This is the case when running the script with blender -P <script-name>.

All the other functions which are using the space_data in scripts/modules/bpy_extras/object_utils.py first check for space_data existence before testing it's type. So it would be consistent to add it here too.

Exact steps for others to reproduce the error

Running blender -b -P object_data_add_bug.py fails with the following traceback :

Traceback (most recent call last):
  File "<pwd>/object_data_add_bug.py", line 4, in <module>                                         
    object_data_add(bpy.context, None, None)
  File "<blender-dir>/2.81/scripts/modules/bpy_extras/object_utils.py", line 134, in object_data_add
    if space_data.type == 'VIEW_3D':
AttributeError: 'NoneType' object has no attribute 'type'
