Fix snapshot manage Tempest test

In the process of managing a snapshot, drivers may want to
rename the snapshot. This could warrant updating the
provider_location as well.

The tempest tests for snapshot manage should not expect that
the provider location will remain unchanged after the driver
has performed the manage operation.
