Error on Pathway Results Tabular View

[chrisknoll]

Expected behavior

When a cohort has no pathways, it should render an empty table.

Actual behavior

The page appears 'broken' with errors in console indicating can not reference property of 'undefined'.
This is similar to an NPE.

Steps to reproduce behavior

1. Create a pathway analysis where the T cohort has zero people.
2. Generate pathway analysis
3. Observe errors when looking at tabular view because no-data is not handled.
