Only show field types if the types are different

[matryer]

To reduce noise, only show the field types if the fields are different.

Do you have an example of what this change would mean?

It says:

expected float64: 200  actual float64: 404

It would be enough to say:

expecte: 200  actual: 404

But keep the types if they are different:

expected string: 200  actual float64: 200
