expression component misbehaves when using Draw Full Names and not changing input names

Hi,

I just noticed some unexpected behaviour in the expression component in Grasshopper 0.9.0076. When adding such a component while Display is set to “Draw Full Names”, the component has errors by default:

'Parameter “Variable x” has an invalid name. Only use alphanumeric characters and don't start with a number.'

'Parameter “Variable y” has an invalid name. Only use alphanumeric characters and don't start with a number.'

While the error messages are helpful, I think it would be nicer not to get this error in the first place – in particular because when using the “Draw Full Names” setting, this also happens when opening existing Grasshopper documents in which the input names for the expression component have not been changed.
