[FLINK-1378] [scala] Fix type extraction for nested type parameters
Before, something like:
def f[T: TypeInformation](data: DataSet[T]) = {
val tpe = createTypeInformation[(T, Seq[T])]
println("Type: " + tpe)
}
f(Seq(1.0f, 2.0f)
would fail because the type extractor could not re-use existing
TypeInformation for nested types.
