Add junit coverage to rest of policy-endpoint bus

Also extracted out common code from tests.
Fix checkstyle issues.
Be consistent in returning IllegalStateException when topic is not
found by any Topic Factory.
Added/updated some comments.
Use better name for "validate" argument.
Renamed test() to testDestroy().
Added NoopTopicPropertyBuilder.
Renamed BusTopicTestBase to TopicTestBase.
