Fix custom validations on 1.2

[eknowles]

This was breaking in Angular 1.2 because the browser dies on $setDirty as this method can not be called as it doesn't exist.

The fix is to check if the version is <= 1.2 and perform the .$dirty / .$pristine on the model.

Coverage remained the same at 70.81% when pulling c2a14be on eknowles:feature/ngModelSetDirty1.2 into e2734c8 on Textalk:development.

Hi @eknowles and thanks for the PR!

But I can't merge this, the files in dist/ are built from the sources, so any changes to it will be overwritten.

But I did fix the bug, you don't need to check version, the if (scope.ngModel.$setDirty()) was there to check for the presence of $setDirty but the extra () meant that it got called instead, so now it's changed to if (scope.ngModel.$setDirty). see:

Perfect! Thank you!
