Refresh failure processing property change for VM `summary.storage.*`

[agrare]

Object: [VirtualMachine:vm-2900512] Kind: [modify] Props: [summary.storage.committed, summary.storage.unshared]
Failed to process property change summary.storage.committed: undefined method `[]' for nil
Failed to process property change summary.storage.unshared: undefined method `[]' for nil

This leads to a nil being passed to the parser which subsequently fails with

 WARN -- evm: MIQ(ManageIQ::Providers::Vmware::InfraManager::Inventory::Collector#parse_updates) Failed to parse VirtualMachine:vm-2900512: undefined method `fetch_path' for nil
ERROR -- evm: [NoMethodError]: undefined method `fetch_path' for nil
