[jira] [HBASE-6007] Make getTableRegions return an empty list if the table does not exist 

Summary:
Making the getTableRegions Thrift API method handle TableNotFoundException and return an empty list in that case. Without this the behavior is dependent on whether an HTable object is present in the thread-local cache in case a table was deleted.

Test Plan: Unit tests
