implement full copy for indexes in batch

Fixed issue in batch mode where CREATE INDEX would not use a new column
name in the case of a column rename.

Indexes were previously being moved to the new table without any
steps to rewrite columns.   We now vendor the copy approach
from table.to_metadata so that there's a new index expressed
in terms of the new columns.
