[SP-1637] - Regression PDI-13102 - Regression: 5.2.0 Database Lookup step - "Unable to get value 'Integer(9)'

Cause: the issue is reproducible when the 'LIKE' predicate is used for lookup.
in this case the cache is ignored and direct database call is performed.
However the db table lookup fails since statefull Database class contains
different row-meta (generated by executing load table SELECT statement)

Resolution: use separate instance of Database class for loading lookup table content
