[SPARK-20439] [SQL] [Backport-2.1] Fix Catalog API listTables and getTable
when failed to fetch table metadata
### What changes were proposed in this pull request?
This PR is to backport https://github.com/apache/spark/pull/17730 to Spark
2.1
--- --
`spark.catalog.listTables` and `spark.catalog.getTable` does not work if we
are unable to retrieve table metadata due to any reason (e.g., table serde
class is not accessible or the table type is not accepted by Spark SQL). After
this PR, the APIs still return the corresponding Table without the description
and tableType)
### How was this patch tested?
Added a test case
