Considering the fact that for a nt:unstructured node, the mixin properties are not removed
when removing the mixin (because they are accepted by the remaining nodetype), I decided to
change my code to remove the properties in all the cases. 

Depending on what has been said before, this should work on nt:unstructured and nt:resoure
nodetypes: 1) remove mixin properties 2) remove mixin 3) save.

But it does NOT. I get the same exception, except that it complains about the second property
of the mixin: javax.jcr.nodetype.ConstraintViolationException: no matching property definition
found for {http://www.day.com/jcr/cq/1.0}lastRolledoutBy

Code executed:

targetNode.getProperty("lastRolledout").remove();
targetNode.getProperty("lastRolledoutBy").remove();
targetNode.removeMixin("cq:LiveRelationship");

Exception is thrown on session.save();

I ran this code on beta4, so with the previous patch.

> When trying to remove a mixin from a non nt:unstructured node (in my case nt:resource),
you get the following exception:
> Unable to alter mixin types: javax.jcr.nodetype.ConstraintViolationException: no matching
property definition found for {http://www.day.com/jcr/cq/1.0}lastRolledout
> lastRolledout property is defined by the mixin cq:LiveRelationship that I am trying to
remove.
