TAJO-1099: LogicalPlanner::convertDataType causes NPE in some cases.
So far, ExprTestBase has not passed through TypeDeterminant in
LogicalPlanPreprocessor. So, unit tests haven't caused this problems.
I fixed the bug and modified LogicalPlanPreprocessor to pass
TypeDeterminant in LogicalPlanPreprocessor. As a result, even though this patch
does not include any unit tests, it is same as all ExprTestBase tests verify
this problem.
