[SPARK-7858] [SQL] Use output schema, not relation schema, for data source
input conversion
In `DataSourceStrategy.createPhysicalRDD`, we use the relation schema as
the target schema for converting incoming rows into Catalyst rows. However, we
should be using the output schema instead, since our scan might be returning
fewer columns due to partition pruning.
This commit adds assertions which expose the bug; I'll post a followup
commit to fix this shortly.
