remote/client: fix named resource matching

`digital_io`, `bootstrap`, `sd_mux`, `usb_mux` and `video` tried to match
against class only instead of class _and_ name if provided.  This lead to
an early fail and an uncaught exception when a resource was found but the
name did not match.

Skip resources whose name does not match.

The `power` sub command had the same issue until commit
ac56062

Fixes labgrid-project#1679
