client: fix extra construction of ColumnSchema

The VARCHAR patches introduced a line 'auto col = schema.column(idx)'
which ends up making a copy of the ColumnSchema object instead of taking
a reference to it. This is unnecessary and quite slow. This shows up as
a significant CPU consumer when running tpch_real_world insert workload.
