As we discussed offline, this PR also enables case insensitive encoder
resolution. Would be nice to add a test case for it. Basically something like
this:
```scala
case class A(a: String)
val data = Seq(
"{ 'A': 'foo' }",
"{ 'A': 'bar' }"
)
val df1 = spark.read.json(sc.parallelize(data))
df1.printSchema()
// root
// |-- A: string (nullable = true)
val ds1 = df1.as[A]
ds1.printSchema()
// root
// |-- a: string (nullable = true)
```
