ng-required conflicts with ng-true-value

[albvalente]

If I set ng-required="something" inside a checkbox, ng-true-value does not work.
This issues happenes with 1.2.x, not with 1.1.x

This should fix the issue: #7377

This is still not working, see this punker with current 1.3.x version (http://plnkr.co/edit/VUAVYLLchaq5bNwgseRp?p=preview)

• unchecking any checkbox (with and without ng-true-value) results in the model to be set to undefined. However: An invalid input should not update the model at all!
• the second checkbox which has an ng-true-value shows an required error on load although it is checked. Unchecking it resets the model as well (which is already wrong), but checking it again does not set the model value to the ng-true-value back.

I'll work on this today.
