[ASTERIXDB-2960][IDX] LOJ array-index INLJ probe PK fix

- user model changes: no
- storage format changes: no
- interface changes: no

Type errors were being thrown for LOJ on subqueries involving UNNESTed
values for array index INLJ. This was due to a bug where we would try to
perform a DISTINCT on probe PK vars that weren't present. If we cannot
infer any probe entries from the context, then insert a UUID on top of
the probe to allow the DISTINCT to work as intended.
