Chomping of Kotlin package declarations doesn't handle backticks correctly

[wilkinsona]

If a Kotlin package name contains a keyword, it can be wrapped in backticks. Boot uses this in its docs where there's a package named object. The result kotlin documentation snippet doesn't fully chomp the package declaration:

`object`

@JsonComponent
class MyJsonComponent {

    class Serializer : JsonObjectSerializer<MyObject>() {
        @Throws(IOException::class)
        override fun serializeObject(value: MyObject, jgen: JsonGenerator, provider: SerializerProvider) {
            jgen.writeStringField("name", value.name)
            jgen.writeNumberField("age", value.age)
        }
    }

    class Deserializer : JsonObjectDeserializer<MyObject>() {
        @Throws(IOException::class)
        override fun deserializeObject(jsonParser: JsonParser, context: DeserializationContext,
                codec: ObjectCodec, tree: JsonNode): MyObject {
            val name = nullSafeValue(tree["name"], String::class.java)
            val age = nullSafeValue(tree["age"], Int::class.java)
            return MyObject(name, age)
        }
    }

}
