Failing test is not actually tested

The test

reach/main/src/test/scala/org/clulab/reach/mentions/serialization/TestJSONSerializer.scala

Line 83 in c7397a4

corefmentions.json(true) == JSONSerializer.toCorefMentions(corefmentions.jsonAST).json(true)

doesn't do anything except calculate the value false. It should instead fail. The bug that causes the false value is actually in processors and will be fixed soon. Still, a test should test.
