Hi, All.
It seems we missed `DROP TABLE IF EXISTS` cases here.
(I also forgot to check that during 2.2-backporting of this PR.)
This PR swallows `NoSuchTableException` and emits `AnalysisException`.
`DROP TABLE IF EXISTS` expected `NoSuchTableException` in ddl.scala. It becomes
a regression on 2.2.1.
