drive: fix incorrect remote after Update on object

Browse Source 
Before this change, when Object.Update was called in the drive
backend, it overwrote the remote with that of the object info.

This is incorrect - the remote doesn't change on Update and this patch
fixes that and introduces a new test to make sure it is correct for
all backends.

This was noticed when doing Update of objects in a nested combine
backend.
