Fix for PCLOUD-189
CSP Prov : Dependent page is displaying 'Sorry, that cloud name is not available. Please try again. ' against cloud name by default ( just after navigation from Home page without performing any action).

On load when dependent cloudname field is null, nameavaibility was returning success = null, and in that condition we are throwing this error.
