[SPARK-19865][SQL] remove the view identifier in SubqueryAlias

## What changes were proposed in this pull request?

Since we have a `View` node now, we can remove the view identifier in `SubqueryAlias`, which was used to indicate a view node before.

## How was this patch tested?

Update the related test cases.
