During thin client refactoring, LocalOrRemote class implementation of `run`
method was overriden by default Command implementation during instantiation of
client plugins from schema. This caused these commands to always forward this
request to IPA master.
This patch restores the original behavior: unless `--server` option was
specified, the commands will always print out local config.
