[SPARK-13709][SQL] Initialize deserializer with both table and partition
properties when reading partitioned tables
## What changes were proposed in this pull request?
When reading partitions of a partitioned Hive SerDe table, we only
initializes the deserializer using partition properties. However, for SerDes
like `AvroSerDe`, essential properties (e.g. Avro schema information) may be
defined in table properties. We should merge both table properties and
partition properties before initializing the deserializer..
## How was this patch tested?
New test case added `QueryPartitionSuite`.
