[BugFix] concat(col) should return cloned column instead of original column to avoid abusing sharing column

[satanson]

Why I'm doing:

Chunk::check_or_die fails since columns in chunk has different sizes.

The root cause is:

In the plan, project operator output both column dept_nbr and concat(dept_nbr), when concat is applied to only one argument, the column is return directly, so dept_nbr appears twice in output chunk of project operator, accumulator operator is descendant of the project operator, it try to merge small chunks into big one via column::append method, so twice-appearing column is appended twice, its size is large than other columns.
