unit_tests: add ipc_context tests

add the initial outline of an ipc_context unit test. The current test
only invokes the ipc_context constructor, more tests will be added later
as the class is being populated.

Also, at the moment the unit test takes an ROBackend as an argument for
the constructor, not sure whether this will be the final solution.
