Title: SCM checkout strategy extension is useless for Matrix projects

Please add following code, otherwise the default SCM checkout strategy would be still used.

/**
* Inherit the value from the parent.
*/
@override
public SCMCheckoutStrategy getScmCheckoutStrategy() {
return getParent().getScmCheckoutStrategy();
}
