LP1842431: Remove redundant description field

This branch brings about a good change, but I think having reason
and description be identical in the case of a failure and blank /
'SUCCESS' in the case of, well, success, is redundant and potentially
confusing. Also, if it's not used in the default template I doubt
anyone ever realizes it's there. :) Template editors can use
is_renewed to decide if they want to display success as a result
and that way the capitalization won't look like THE EIGHTIES have come
back in fashion again. :D
