Eliminate uses of ModelNode.resolve()

Code inspection shows there are 23 uses of ModelNode.resolve() in WildFly's own code base, 12 in production code and 11 in test code. We should eliminate these, as WildFly's expression resolution is more complex than the ModelNode.resolve() contract, including vault support for which its' hard to imagine us wanting support in DMR itself. So these uses should switch to resolution from the OperationContext or, if that's not feasible, e.g. in test code, use something like ExpressionResolver.TEST_RESOLVER.
