If a cycle has length 1, don't enumerate the single cycle entry;
instead just mention "refers to itself". For instance, for an
invalid recursive type T we now report:
invalid recursive type: T refers to itself
instead of:
invalid recursive type T
T refers to
T
Adjust tests to check for the different error messages.
