Simplify unit tests

Almost all acceptance tests define verbose boilerplate code to inject
and initialize common parts, like project, ssh session, user, REST session,
review db and git.

This change moves that code to the base class. Now the boilerplate code
can be removed, as in ProjectIT:

 public class ProjectIT extends AbstractDaemonTest  {

-  @Inject
-  private SchemaFactory<ReviewDb> reviewDbProvider;
-
-  @Inject
-  private GerritApi gApi;
-
-  @Inject
-  private AcceptanceTestRequestScope atrScope;
-
-  @Inject
-  private IdentifiedUser.GenericFactory identifiedUserFactory;
-
-  private ReviewDb db;
-  Project.NameKey project;
-
-  @Before
-  public void setUp() throws Exception {
-    project = new Project.NameKey("p");
-    SshSession sshSession = new SshSession(server, admin);
-    createProject(sshSession, project.get());
-    db = reviewDbProvider.open();
-    atrScope.set(atrScope.newContext(reviewDbProvider, sshSession,
-        identifiedUserFactory.create(Providers.of(db), admin.getId())));
-  }
-
-  @After
-  public void cleanup() {
-    db.close();
-  }
-
