The test causes a Log.wtf to be logged, because it tests a method that
should not be used after R. Mock the terrible failure handler to avoid
crashes on eng builds.

Move the tests together with packages/Connectivity code, so both can be
moved to packages/modules/Connectivity together.
Also reorganize unit tests in a unit/ directory, as other tests
(integration/, common/ etc.) have been added in tests/net since they
were created. This makes the directory structure consistent.
