[ASTERIXDB-3159][STO] Fix point lookups on columnar dataseet
- user model changes: no
- storage format changes: no
- interface changes: no
Details:
This patch fixes the issue of running out of values
when point lookups are performed against columnar
datasets. The issue was that the next point lookup
(using the stateful batch point lookup) would
proceed without testing if:
- the tuple key == the required key
