Delete all answer sets bug

[ladracer]

Describe the bug

It seems that if a user selects to delete all saved answer sets WHEN THERE ARE NO ANSWER SETS an error is generated.

To Reproduce
Steps to reproduce the behavior:

1. Go to Answer Sets
2. Click on Delete All Answer Sets
3. Repeat (Click on Delete All Answer Sets)
4. See error

Expected behavior
A message saying that there are currently no answer sets or perhaps even better would be "All answer sets have been deleted."
