The CrOS file picker closes the dialog immediately, without running the page unload handler.  This meant we were leaking file watcher objects, causing a DCHECK in SelectFileDialogExtensionBrowserTest.  Fixed by calling it manually when needed.

Also, we need to clean up the current directory's watcher, because we don't have a directory-change event in the unload handler that we can use to look up the directory path.
