Many unit tests for `AssessPhasing` rely on a broken test fixture

[clintval]

The test fixture used to create a single-interval IntervalList, despite allowing parameterization, always returns an interval in the range [1, 10]. Fixing this bug causes many unit tests to fail. Either the implementation of AssessPhasing is incorrect or the test cases were create improperly such that they assert incorrect expected test outcomes.
