/**
 * @assertion Future<FileSystemEntity> delete({bool recursive: false})
 * Deletes this FileSystemEntity.
 *
 * If the FileSystemEntity is a directory, and if recursive is false, the
 * directory must be empty. Otherwise, if recursive is true, the directory and
 * all sub-directories and files in the directories are deleted. Links are not
 * followed when deleting recursively. Only the link is deleted, not its target.
 *
 * If recursive is true, the FileSystemEntity is deleted even if the type of the
 * FileSystemEntity doesn't match the content of the file system. This behavior
 * allows delete to be used to unconditionally delete any file system object.
 *
 * Returns a Future<FileSystemEntity> that completes with this FileSystemEntity
 * when the deletion is done. If the FileSystemEntity cannot be deleted, the
 * future completes with an exception.
 * @description Checks that if recursive is false, the FileSystemEntity is not
 * deleted if the type of the FileSystemEntity doesn't match the content of
 * the file system. Test Link
 * @author sgrekhov@unipro.ru
