CLI2: Fixed bug in ::findCommand

- If an argument is an exact match for a command ('projects'), it is a command.
- If an argument is not an exact match for command ('project'), but is an exact
  match for an attribute, it is not a command.
- If an argument fails the above tests, but canonicalizes to a command, it is a
  command.
