[SPARK-16224] [SQL] [PYSPARK] SparkSession builder's configs need to be set
to the existing Scala SparkContext's SparkConf
## What changes were proposed in this pull request?
When we create a SparkSession at the Python side, it is possible that a
SparkContext has been created. For this case, we need to set configs of the
SparkSession builder to the Scala SparkContext's SparkConf (we need to do so
because conf changes on a active Python SparkContext will not be propagated to
the JVM side). Otherwise, we may create a wrong SparkSession (e.g. Hive support
is not enabled even if enableHiveSupport is called).
## How was this patch tested?
New tests and manual tests.
