Fix for initial folder in FileDialog.open()

Hi,
after updating our application to Eclipse 2021-09 the setFilterPath does not work anymore. The directory used by the dialog seems to be random. 

I found out that this is probably caused by bug 571571. 

A fix could be adding fileDialog.ClearClientData() before calling fileDialog.SetDefaultFolder(psi) in FileDialog.open():

/* Set initial folder */
if (filterPath != null) {
   char[] path = (filterPath.replace('/', '\\') +"\0").toCharArray();
   if (COM.SHCreateItemFromParsingName(path, 0, COM.IID_IShellItem,ppv) == COM.S_OK)
   {
     IShellItem psi = new IShellItem(ppv[0])
     /*
      * SetDefaultFolder does not work if the dialog has
      * persisted recently used folder. The fix is to clear the
      * persisted data.
      */
     fileDialog.ClearClientData();
     fileDialog.SetDefaultFolder(psi); 
     psi.Release();
   }
}

I found this by comparing FileDialog with DirectoryDialog as mentioned in this stackoverflow question:
