Bug 31095: (Rebase follow-up) Correct fine rules and AddIssue calls

This patch corrects the errant call to AddIssue that passes a patron
object instread of a patron hash to AddIssue in the tests and also adds
lengthunit to squash a pair of warnings.

However, it doesn't resolve the failing test.. still somthing going on
there.
