Ignore invalid display directories in FilePicker

Browse source 
As of Firefox 140.17/153.4 (Bug 2068406), setting nsIFilePicker's
displayDirectory to a directory that doesn't exist or isn't readable
throws instead of being ignored. This broke callers that pass a saved
path that may be stale (e.g., choosing a PDF/EPUB handler after the old
app's folder was removed, or a missing Scaffold translators directory).

(cherry picked from commit ae50d52589)
