[SPARK-22529] [SQL] Only sizeInBytes in catalog stats needs to be
propagated when cbo is disabled
## What changes were proposed in this pull request?
When CBO is disabled, we apply the size-only estimation strategy, so
there's no need to propagate other statistics from catalog to the plan.
## How was this patch tested?
Enhanced existing test case.
