Fixes #4135
Fixes #4136

Proposed Changes

• Fall back to getFile().getName() in HybridFile.getName(Context) when mode == OpenMode.TRASH_BIN and name is null or empty (such as when constructed via new HybridFile(OpenMode.TRASH_BIN, path) in AppConfig.getTrashBinInstance()).
• Guard HybridFile.toTrashBinRestoreFile(Context) against a null TrashBin instance or empty file name.
• Guard HybridFile.deletePermanentlyFromBin(Context) when toTrashBinRestoreFile(Context) returns null so a singleton list containing null is not passed to TrashBin.deletePermanently(...).
