cli: "result list": Only display name fields with --all

The user-friendly unique ID, as displayed for each object, when running
"result list", includes the (non-unique) name. In fact, in the common
case, when the name happens to be unique, the ID and the Name are the
same. So it's somewhat redundant and confusing to list both by default.

Let's hide the Name when --all is not given to simplify things a bit.
Note that for the benchmark case, both the suite and name are used to
form the ID, so hide both.
