provide nicer feedback when an unknown node id is passed to a command

Previously, an unknown node id would lead to the following error:
abort: 00changelog.i@343445453433: no node!

All other unknown revision would instead display as:
abort: unknown revision '343445453'!

The former error message has been suppressed in favor of the latter.
