Bug 22045: (follow-up) Revert change to numbering of tabs

I wanted the tabs to be numbered like humans count, starting from 1.
But if the MARC framework setup isn't changed as well it doesn't make
sense. This patch removes the change.

Also fixed: Some missing template filters, an errant console.log()
removed.

To test, apply the patch and open a new or existing record for
editing. The tabs (now "Sections") should be labeled from 0-9.
