Fixes strange rubric rendering with set passing score

[jpeterson976]

Fixes #1863

It didn't seem to like when the attempt score was 100 but the rubric sets the score to >100 when passing, so I added a new display type for that case that gives the same info as when the attempt score is less than 100 but passes.

There might be a simpler way to tackle this - I'm thinking we merge these:

TYPE_PASSFAIL_PASSED_GIVEN_SCORE_AND_ATTEMPT_SCORE_LESS_THAN_100,
TYPE_PASSFAIL_PASSED_GIVEN_SCORE_AND_ATTEMPT_SCORE_IS_100_AND_NO_MODS_REWARDED,
TYPE_PASSFAIL_PASSED_GIVEN_SCORE_AND_ATTEMPT_SCORE_IS_100_AND_MODS_REWARDED,

Into just one: TYPE_PASSFAIL_PASSED_GIVEN_SCORE

And it would replace the case in the switch for TYPE_PASSFAIL_PASSED_GIVEN_SCORE_AND_ATTEMPT_SCORE_LESS_THAN_100.

That way any time a score is strictly set for meeting the threshold score it would always render as

Attempt Score (Passed): xx%
--------
Score adjusted for passing: yy%

I think the code as it is is attempting to avoid situations where the set score is equal to the attempt score (So students don't see text like Score: 100%, Score adjusted for passing: 100%), but with the ability of hindsight I think that was probably a bad decision. If we don't care about it, it will simplify the code and remove this problem

I tried all the combination of rubrics I could think of, all working great. I merged in the latest dev/25 changes and assuming the tests past I'll merge in
