Update unit tests to reference logo.png instead of trophy.png.
Review Request #8322 — Created Aug. 12, 2016 and submitted
Many of our unit tests that deal with file attachments are referencing trophy.png as a sample file. An upcoming change will be removing this file, which will break the tests. This change swaps out those references to use logo.png instead, in order to keep tests from failing.
Unit tests pass.
