-------------------------------------------------------------
1. Fixed the failed tests.
2. Add a test based on [~pxiong]'s suggestion, the test scenario is as
following (see encryption_move_tbl.q):
When renaming a table fails to move its table data from one encryption zone to
another due to EZ incompatibility, table rename fails but its column stats are
invalidated. When we describe formatted table column, we found that all column
stats have gone.
[~pxiong] could you review it to see if it makes sense? Thanks.

> If the table rename does not succeed due to its failure in moving the data to
> the new renamed table folder, the changes in TAB_COL_STATS are not rolled
> back which leads to invalid column stats.
