Change salesforce module properties to minimize calls to Salesforce

Currently the studio is avoiding certain UI calls as a way to minimize the calls to afterModuleName since it blindly contacts salesforce to get the schema implementation. We can add a beforeModuleName to remember the current value of the moduleName property and the afterModuleName need refresh the schema only if the schema is either not populated or the module name changed.

Then the studio can function normally for this component.
