Adjust infix tests for new rule
Adjust infix tests for new rule

The new rule is that infix only dispatches when it's called from a
word--but dispatches prefix when composed into a block directly as
a literal value.

(Whether this is the permanent rule or not is up in the air, but it
is a way of keeping things working under the NewEvaluator interface
used internally by Ren-C, which has no "apply" and can only put
functions at the head of evaluation chains.)
