cue: treat disjunctions as normal non-concrete values

This brings the implementation in line with the spec
relating to the treatment of default values.

Before getting a default resulted in a "multiple
values remaining" error if the value was a disjunction.
However, there is nothing special about such
disjuctions compared to any other non-concrete
value. Generating an error early resulted in some
strange and sometimes spurious error messages.

Issue #52
