TL;DR

Handle Scala Option correctly by using correct type.

Complete description

For case classes like:

case class ScalarNested(
    foo: String,
    bar: Option[String],
    nestedNested: Option[ScalarNestedNested]
)
case class ScalarNestedNested(foo: String, bar: Option[String])

the current code doesn't handle typing correctly because calling param.typeSignature.dealias.typeArgs.head.typeSymbol on Option type does not give what we need, and it should be param.typeSignature.dealias.typeArgs.head instead.

Also we are not handling nested Option correctly, although in practice there is no good reason to define Option[Option[String]].

This is another bug fix. We have been converting things into Some(None), due to type conformation test failure against T in Option[T], which is exactly what this PR set off to fix. Bug on top of bug :(

Hopefully the extended unit tests and ITs cover better.
