Bug 24698: QA fixes

This is a squashed patch of the following patches:

Bug 24698: (QA follow-up) Fix errors caused by more strict exports being introduced

The original patch "Bug 24698: Add plugin and template files for
unimarc authority leader" doesn't work without explictly importing the
methods from C4::Auth and C4::Output due to the default exports being
changed in those modules after the patch was made.

Bug 24698: (follow-up) remove HTML select option for Series

The IFLA authorities format specification defines only the letters a-l
as possible values for authority leader 000 character position 9 ("Type
of entity"). Therefore, the first option from the HTML select dropdown
menu (" - Series") must be removed.
