test(sync): test devices sync through their sync service

Browse source 
A test device synced by calling the engine itself, so its repositories
never heard of what a sync merged; reading the database each time, they
didn't need to. Since cards and reviews are kept until something changes
them, a device went on reading its cards from before the sync, and the
conflict test failed. Devices now sync through their SyncService, as the
app does, and fail when the sync failed. SYNC_TEST_SERVER_DIR names the
server folder whose database the SQL checks read, for a worktree testing
against another checkout's running server. All 30 sync tests pass.
