Transforming into case class with mutable field breaks from 0.8.0

Checklist

• I read the documentation at https://chimney.readthedocs.io/ and checked that the functionality exists
• I verified that the behavior for my use case doesn't match the documentation
• I checked the https://github.com/scalalandio/chimney/issues and haven't found the issue reported
• I confirmed that the bug is not related to functionality that was deprecated: lifted transformers (TransformerFs) or unsafeOption flags

Describe the bug
Transforming into a class with a mutable field no longer works as of 0.8.0 - I did not find this in a list of removed functionality

Reproduction
The following works in 0.7.5, fails to compile on 0.8.0

object Main extends App {
  def fromRow(row: Bar): Foo = row.transformInto[Foo]
}

case class Foo(var string: String)

case class Bar(string: String)

Expected behavior
As per the documentation 'every class with a public primary constructor can be the target of the transformation.' - a case class with a mutable field is very much a class with a public primary constructor - I would expect this to continue to work as before

Actual behavior

~/chimney_min_bug/src/main/scala/chimney_min_bug/Main.scala:7:49: Chimney can't derive transformation from chimney_min_bug.Bar to chimney_min_bug.Foo
