Qmlls makes QQmlJSImportVisitor re-create a QQmlJSScope when a file gets updated. It turns out that QQmlJSImportVisitor only works correctly when used on an empty scopes, methods like rootScopeIsValid() don't work correctly if the scope is not empty. Therefore, reset the scopes before making QQmlJSImportVisitor run on them. Make sure that the internalName and the moduleName are still set. This fixes a bug where qmlls can't autocomplete an "in-memory" enum because the import visitor does not set the new enum values in the root element correctly on an non-empty scope.
