Fix 'No assessments' message when there are assessments

[cemalettin-work]

This pull request solves the issue of showing "No assessments" message in the assessments' table when there are assessments to show. Assessments are divided into two groups when dealing with user feedback. "Engagement Assessments" and "Periodic Assessments".

The reason for the previous behavior was that both of these assessments are evaluated separately but only engagement assessments returned a user feedback. Now both return a user feedback.

Note: If there is no config for "Engagement Assessments" or "Periodic Assessments", we don't show "No engagement/periodic assessments" message, as that task/person isn't even configured for such assessments.

We can also show "No engagement assessments" or "No periodic assessments" even if that task/person isn't configured to show those. I am open to suggestions.
