Fix empty 'more values' popup for internal attributes

[MGSousa]

The "N more values ..." popup modal populates its list purely client-side, by scraping hidden <input> elements already rendered on the page for the given attribute.

Internal/operational attributes of memberof are rendered under a separate container, div#internal (on resources/views/frames/dn.blade.php), not div#template-default. As a result, clicking "N more values ..." on any internal attribute with more values than pla.limit.values always opens an empty popup, since the selector never matches anything.

Thus the fix to drop the div#template-default prefix from the selector so it also matches attributes rendered under div#internal.
