Title: treat Option as CollectionLike in ScalaObjectMapper

This will ensure that the custom OptionDeserializer is always used when deserializing Options.
Right now when `List[Option[_]]` is deserialized, the Option class is treated as a "simple" type in the constructed `JavaType` and thus a generic JSON Deserializer is used rather than `OptionDeserializer`.
Note that the new test will NOT pass until a jackson-databind dependency with https://github.com/FasterXML/jackson-databind/pull/407 is used
