IMPALA-9095: Alter table events generated by renames should apply renames
properly.

A recent change refactored alter table event handler for rename operations
which introduced a bug that causes renames to a different db to be applied
incorrectly to the same db. This change adds a check to see if both the old
db and the new db are in catalog and applies the change to newdb properly.

Testing:
1. We did not have a rename testcase that crossed a single db. Added a test
   case for renaming to a different db.
2. Ran MetastoreEventsProcessorTests.

> Alter table renames was recently refactored. This introduced a bug where rename to a different database is not applied correctly.
> Steps to reproduce:
> From Hive:
> {code:java}
> create database bug1;
> create table bug1.foo (id int);
> create database bug2;
> alter table bug1.foo rename to bug2.foo;{code}
>  
> From Impala:
> {code:java}
> use bug2;
> show tables;{code}
>  
> Expect foo to show up in bug2, it doesn't.
