Entity extraction pivot feature not working

[smahoney58]

The pivot feature for highlighted entities in the email body is not working. The user should be able to select one of these highlighted entities and pivot/re-query based on selection.

Steps to Reproduce

• Search for "test" to retrieve all 9 emails in the test dataset
• Select the search results and then the second email in the list "test email"
• Select the highlighted John Doe
  Expected the system to re-query the dataset for "John Doe" instead nothing happens.
