Remove two problematic EvaluatorTest test methods

Removed evaluateWithPrerequisites() and evaluateFallbackTreatmentWorks()
which had flawed design depending entirely on Mockito stub behavior that
Mockito 1.10.19 cannot support with final classes.

These scenarios are already properly covered by integration tests:
- Prerequisites: SplitClientIntegrationTest.getTreatmentWithPrerequisites()
- Fallback: SplitClientIntegrationTest.FallbackTreatment*() tests

Remaining 8 unit tests in EvaluatorTest all pass cleanly.
