`IndexingRescanner` doesn't generate `DELETED` events for content items of moved/renamed directories

To reproduce

// Create file tree
var parent = Files.createTempDirectory("");
var child1 = Files.createDirectories(parent.resolve("from"));
var child2 = Files.createDirectories(parent.resolve("to"));

// Create directory to be moved
var directory = Files.createDirectory(child1.resolve("directory"));
Files.createFile(directory.resolve("file1.txt"));
Files.createFile(directory.resolve("file2.txt"));

// Start a watch for the whole file tree
try (var watch = Watch
        .build(parent, WatchScope.PATH_AND_ALL_DESCENDANTS)
        .onOverflow(Approximation.DIFF)
        .on(System.out::println)
        .start()) {

    // Move directory
    var source = child1.resolve(directory.getFileName());
    var target = child2.resolve(directory.getFileName());
    Files.move(source, target);

    // Wait for events
    Thread.sleep(30000);
}

System.exit(0);

Expected output

DELETED events for file1.txt and file2.txt.

Actual output

No such events:

WatchEvent[C:\Users\sung-\AppData\Local\Temp\16629189291729839418, DELETED, from\directory]
WatchEvent[C:\Users\sung-\AppData\Local\Temp\16629189291729839418, CREATED, to\directory]
WatchEvent[C:\Users\sung-\AppData\Local\Temp\16629189291729839418, MODIFIED, to]
WatchEvent[C:\Users\sung-\AppData\Local\Temp\16629189291729839418, OVERFLOW, to\directory]
WatchEvent[C:\Users\sung-\AppData\Local\Temp\16629189291729839418, CREATED, to\directory\file1.txt]
WatchEvent[C:\Users\sung-\AppData\Local\Temp\16629189291729839418, CREATED, to\directory\file2.txt]

Commencez par le comportement de IndexingRescanner exercé par la reproduction Java dans l’issue, en vous concentrant sur la gestion du déplacement de répertoires et le traitement des diffs d’overflow. Reproduisez le déplacement avec un watch récursif, puis vérifiez que des événements DELETED sont émis pour file1.txt et file2.txt en plus des événements de répertoire existants.
