Bug 15758: [QA Follow-up] Final touch?

From qa tools:
reports/cat_issues_top.pl: pod: =over on line 39 without closing =back

Note: qa tools does also report "options_for_libraries: not found" on two
template includes. Considering this as a false alarm, since the block is
defined in another include loaded in doc-head-open.
[1] koha-tmpl/intranet-tmpl/prog/en/includes/subscriptions-search.inc
[2] koha-tmpl/opac-tmpl/bootstrap/en/includes/opac-topissues.inc

Found a template where a USE Branches was missing:
koha-tmpl/intranet-tmpl/prog/en/modules/serials/subscription-add.tt
Easy to spot since the libraries combo was empty.
Tried to find similar occurrences with few greps, but couldn't find any.

I did find duplicate USE Branches though in:
koha-tmpl/intranet-tmpl/prog/en/modules/admin/smart-rules.tt
koha-tmpl/intranet-tmpl/prog/en/modules/serials/checkexpiration.tt
This patch removes them.
