[SPARK-15185] [SQL] InMemoryCatalog: Silent Removal of an Existent
Table/Function/Partitions by Rename
#### What changes were proposed in this pull request?
So far, in the implementation of InMemoryCatalog, we do not check if the
new/destination table/function/partition exists or not. Thus, we just silently
remove the existent table/function/partition.
This PR is to detect them and issue an appropriate exception.
#### How was this patch tested?
Added the related test cases. They also verify if HiveExternalCatalog also
detects these errors.
