"Error: Call to a member function getRowCount() on array" during cron ron

I had a look into the code. It looks like the cache handling in method gacGetFeed .
This method should return RunReportResponse, but returns an array in case the results are cached.

Thank you! - Given that I introduced this error it seems only proper I test it. Yeah I didn't catch it since it involved having to wait long enough to have a cached response, but I was getting the same error today when developing locally, a work around was to clear cache before running cron.

But I tested the patch and it works.

For me it logged as having invalid or empty data. So I do wonder if the cache-data is working correctly... I may dig into this a bit deeper today.
