TC4A: homescreen shortcut for empty zip behavior

[DrShark]

To reproduce:
1) make empty (0-byte) file with zip extension;
2) make "Create link on desktop" archive context menu item make a shortcut on Android Home screen;
3) try to open the shortcut: it will open TC4A with active panel in home (aka Root) folder.

I would like to suggest to open TC4A in file's parent folder in this case (this will be also similar to desktop TC behavior after executing cd command which, if TC fails to open the file as archive, makes TC to open the folder where file is located and places the cursor on the file.)
