fix(panic): gracefully handle if we can't find a Release

Sometimes upstream pushes a commit without %{dist} in Release, which has
a side effect of breaking Peridot/srpmproc due to Peridot trying to
extract information based on the tag, and the tag not having this
information.

This change adds error handling for this situation
