Created Issue: Qulified name should be used to call a function/action. [1638]

According to the OData protocol, functions and actions should be called with namespace- or alias- qualified name. For example:
To invoke an action bound to a resource, the client issues a POST request to an action URL. An action URL may be obtained from a previously returned entity representation or constructed by appending the namespace- or alias-qualified action name to a URL that identifies a resource whose type is the same as, or derives from, the type of the binding parameter of the action.
But currently, it doesn't report error if the namespace or alias is not specified, for example:
~/Employees(1)/GetAccessLevel
