Update FinalStatsReport to reflect format changes

FinalStatsReport uses
ActiveRecord::Base.connection.select_all(query_string).to_hash
to get its raw materials from the database. This provides an array of
hashes, one hash for each result.

Formerly, the values in these hashes would all be strings (or nil). An
integer value of 3 would come back as '3'; Booleans would be 't' or 'f'.

In Rails 5, the values come back in their original formats.

This commit adjusts the data processing to reflect the format change
(including removing the now-obsolete 'booleanize' method). It also
refactors a bit, eliminating the need for a Rubocop exception.
