Kotlin immutable classes cannod be modified in v3

Looks like something is changed and for the cases like this when Kotlin generates multiple constructors, the empty one is being picked up in v3, preventing modifying the bean with `withValue` method.
```
@MappedEntity
data class SomeEntity(
@field:GeneratedValue
@field:Id
val id: Long? = null,
val something: Int? = null
)
```
The workaround is to remove the defaults:
```
@MappedEntity
data class SomeEntity(
@field:GeneratedValue
@field:Id
val id: Long?
val something: Int?
)
```

I think we should change how we select the bean constructor, we should prefer the constructor that is able to initialize the maximum about of the immutable properties.
