[SPAKR-16004] [SQL] improve the disply of CatalogTable information
## What changes were proposed in this pull request?
A few issues found when running "describe extended | formatted [tableName]"
command:
1. The last access time is incorrectly displayed something like "Last
Access Time: |Wed Dec 31 15:59:59 PST 1969", I think we should display as
"UNKNOWN" as Hive does;
2. Owner is always empty, instead of the current login user, who creates
the table;
3. Comments fields display "null" instead of empty string when commend is
None;
## How was this patch tested?
Currently, I have manually tested them - it is very straight-forward to
test, but hard to write test cases for them.
