shill: wifi cleanups

three cleanups:
- WiFi and WiFiService: rename deferred task handlers (RealScanDone
  and RealConnect) from Real<Func> to <Func>Task. this makes them
  consistent with the naming in Modem.

- WiFiMainTest:
  - use scoped_ptrs (rather than bare) for references to mock
    proxies. this simplifies memory management, and makes WiFiMainTest
    more consistent with DHCPConfigTest
  - eliminate "uninteresting mock function call" messages
