[SPARK-18947][SQL] SQLContext.tableNames should not call Catalog.listTables
## What changes were proposed in this pull request?
It's a huge waste to call `Catalog.listTables` in `SQLContext.tableNames`, which only need the table names, while `Catalog.listTables` will get the table metadata for each table name.
## How was this patch tested?

Closes #16352 from cloud-fan/minor.
