[BUGFIX] Prevent Uncaught TypeError in Recordlist JavaScript

Since translated records do not contain a checkbox
for the clipboard functionality, we have to check the
element before accessing the "checked" property.

Note: There is still a problem in master, which will
be tackled in a separate patch.
