In the PR https://github.com/apache/spark/pull/15682, we identified an
issue when we try to uncache a view that containing a table that has been
dropped. We are not issuing `NoSuchTableException`. Instead. Instead, we issue
an `AnalysisException`. That means, this might not cover all the senario. Do
you want to cover that case in this PR?
