Tabular files with a single row don't show up properly in data_sets 1 file browser

[scottx611x]

• Specific code commit: fad81a2
• Version of the web browser and OS: Chrome Version 53.0.2785.143 (64-bit)
• Environment where the error occurred (Vagrant VM and site conf mode or AWS instance): https://test.stemcellcommons.org

Steps to reproduce

1. Upload this comma delimited file (or any other tabular file referencing a single data file) into Refinery: sample-comma.txt
2. View the File Browser at https://test.stemcellcommons.org/data_sets/<uuid>:
   • See no files displayed (no console errors):
3. View the File Browser at https://test.stemcellcommons.org/data_sets2/<uuid>:
   • See the proper behavior:
     

Observed behavior

• I haven't exhausted all edge cases but it seems that tabular files that reference a single data file, regardless of delimiter type, aren't displayed properly in the data_sets file broswer, but are displayed properly in data_sets2 file browser

Expected behavior

• For the data_sets file browser to be able to handle tabular files referencing a single data file.

I'm currently not able to reproduce this issue locally in gdev mode.

But I am able to see the issue in prod mode

Some Context: Solr sends back an additional 400 error in the data_sets 1 filebrowser when there is only one row defined in the metadata since full_response.content has no facet_fields. Handling
this one-off case for now seems sufficient in my eyes since the way data_sets 2 filebrowser interacts with Solr doesn't produce this extra 400 error.

Fixes are encapsulated within #1479
