Bug 34251: When using the fast add framework in addbiblio.pl there is thrown a JS error in selectTab( "#tab0XX_panel" );

This is because no nav tabs are build in addbiblio.tt as BIG_LOOP has a
length(size) of 1

To test:

1) go to More>Cataloging
2) click +New record
3) Click Settings> Fast add framework
4) take a look on console
5) try selecting a different framework now, will have no effect
6) apply patch and redo steps 1 to 5
7) there should be no error in console and a change in settings works a
   expected
