Handle NotFound error for GetSubTreeById

Currently, PowerSupplies handling is done via `GetSubTreeById` and it
returns the success with the empty collection, even if the given chassis
is invalid.
```
GET /redfish/v1/Chassis/INVALID/PowerSubsystem/PowerSupplies
```

Once phosphor-objmgr is fixed by [1], the above URI will cause an
internalError.

This commit is to handle the case as NotFound error for the invalid
chassis with [1], and fixes the common error [2].

Tested:
- GET /redfish/v1/Chassis/INVALID/PowerSubsystem/PowerSupplies with
  NotFound.
- Redfish Service Validator passes
