Makes the dependency explicit in the TelemetrySession's interface instead of making it a hidden dependency. This also revealed a hidden issue with the way the telemetry session was being initialized. It was attempting to retrieve the app loader and log out title-specific information. However, this isn't always guaranteed to be possible. During the initialization phase, everything is being constructed. It doesn't mean an actual title has been selected. This is what the Load() function is for. This potentially results in dead code paths involving the app loader. Instead, we explicitly add this information when we know the app loader instance is available.
