fix: mapView should not be exported at root level

[vietnguyen]

https://dhis2.atlassian.net/browse/DHIS2-20266

Issue

• User reported that when export metadata with Map and MapView, then import again, server throw duplicate exception because MapView included at root level and also inside Map object.

Fix

• The issue happens because MapView is both embedded object and identifiable object.
• This PR fix the issue by remove the MapViewSchemaDiscriptor, this will exclude MapView from the root level of the metadata export.
• This PR also remove the AbstractCrudController from MapViewController so this object can only be imported as a collection of Map object through MapController.

Test

• Added test and existing test in MapControllerTest also passed.
