Subject: [PATCH] Revert "Make index not unique (#537)"

This reverts commit c89c18f64124b78d3bb66e3f4a1fffec748bbfc2.

I decided that since the code is written
with the assumption that there is only one
issue per person that I would revert this.
If the logic changes I will change this to
non-unique.
