Extend Restorer Acceptance Tests

[ekcasey]

Add acceptance tests for restorer.

Should include tests for both image and directory type caches.

[natalieparellano]

The existing tests cover a limited set of functionality. We should extend them.

The tests should run on Linux and Windows. They should cover most command invocations (see Detector & Analyzer as examples) and should include a test of the exit code in case of error (see Detector as an example).
