Fix Maximize Portrait Scenario + Snap Resize not finding traces

Forgot to actually set the display rotation for each maximize flicker scenario, so every scenario was in the same orientation. Snap Resize scenarios sometimes can't find the trace, might be because of there not being a clear point where the scenario stops due to not having the test setup rule to start a new activity.
