Fix issue in API `POST /services/(id or name)/update` 

This fix tries to address the issue raised in 26090 where
remote API `POST /services/(id or name)/update` cannot
use `name` to update. This is not consistent with the
documentation of the remote API.

This fix fixes this issue by performing a lookup with `getService`
in case `name` instead of `id` is used in API.

This fix adds an integration test to cover the changes.

This fix fixes 26090.
