After upgrading to 2.7 I got plenty of deprecation messages which I could not assign directly as I have updated all of my FormTypes.

Whit this minor improvement the actual class will be show so the upgrade will be much easier.

I think same should be considered in other deprecation errors as it gets more difficult to trace down if external libraries are involved.
