Keep setIcon() working for now on PHUIObjectItemView

Summary:
Ref T11501. This method was removed in D16418, but still has some callsites. I know of four:

  - Config
  - Settings
  - Drydock main page
  - Almanac main page

Since I might be missing some and it's close to the release cut, just put the method back for now until we can clean it up more properly.

Test Plan: Viewed Settings, Config, Drydock, Almanac. No more fatal on this method being missing.
