> The listUsageRecords API command, pulls down the list of usage records in the cloud_usage database and augments records with information pulled from the cloud database.
> When dealing with instance records, only instances which are do not have a value for the removed field are considered. Unfortunately, since the output of _entityMgr.findById is not checked this means that Null Pointer Exceptions are generated when trying to access the output for expunged VMs.
> The attached patch fixes the issue and applies a similar fix for other similar cases.
