Accidentally removed .metadata from gitignore
Update ConnunicatorTests so JUnit tests fail properly

Any assertion checks associated with the JUNit test need to exist in the @Test
function itself, otherwise JUnit will never register them as failures.

Note that you only really need to call enqueueJob() in order to enqueue a job
that you want to run inside of Nachos.  Moreover, since this queue is blocking,
you can be sure that any assertions you place after calling it will be executed
only after the enqueued job has completed.
