fix(cli): Fix app resolution - respect owner in config

The backend refactor that removed global aliases was not fully reflected
in the CLI, breaking "wasmer app get" and similar commands that all back
the reading the local app.yaml file.

This commit

* Removes the `Alias` variant of AppIdent, since there conceptually are no global
  aliases anymore, just domains

* Makes the resolution respect the `owner` in the config

* Falls back to trying to get the app by name with the current user as
  the owner
