can we get some tests?

[manodnyab]

should we send the metric here too?

[samgst-amazon]

There is a metric already being emitted in DiskCache for when loadRegistration fails, and because we are passing in source.REFRESH_TOKEN we already have a metric that tells us when this specifically is happening (vs when it always fails upon first initialization). Assigning null here will also emit this metric here. I'm not sure it needs another metric emitted
