Consolidate "Not Synced" error messages:

Work on a version 2 of the XRP Network API has begun. The new
API returns:

* `notSynced` in place of `noClosed`, `noCurrent`, and `noNetwork`;
* `invalidParams` in place of `lgrIdxInvalid`.

The new version 2 API cannot be selected yet, as it remains a work
in progress.

Fixes #3269
