[SQL] [Minor] Tests the data type conversion code paths
In `SimpleTextRelation`, we specified `needsConversion` to `true`,
indicating that values produced by this testing relation should be of Scala
types, and need to be converted to Catalyst types when necessary. However, we
also used `Cast` to convert strings to expected data types. And `Cast` always
produces values of Catalyst types, thus no conversion is done at all. This PR
makes `SimpleTextRelation` produce Scala values so that data conversion code
paths can be properly tested.
