Bug: Some dashboard types don't have a "name" attribute

[bmtcril]

When importing the mockup dashboard I ran into the following:

  File "/app/pythonpath/create_assets.py", line 231, in generate_translated_dashboard_filters
    translation = get_translation(filter["name"], language)

The issue is that DIVIDER types don't have a name, but they do have a description we could key translations off of so we should check for both.
