Use Sexp#mass for issue mass, not Flay::Item#mass

Better matches Classic.

Additionally, stop penalizing extra for duplicated code that is identical,
as its remediation effort should be the same or less than that of similar code.

 ## Issue Mass
 
 Duplicated code has a calculated mass, which can be thought of as a measure of how much logic has been duplicated.
-This issue has a mass of `<%= issue.mass %>`: if you would like to change the minimum mass that will be reported as an issue, please see the details in [`codeclimate-duplication`'s documentation](https://github.com/codeclimate/codeclimate-duplication).
