Jonathan Druart 927aedafa1 Bug 10985: [UNIMARC] Fix authority summary
The problem is the template in authority type summary is not respected
at all. It is only read to see which fields and subfields should appear
in the summary.
This patch fixes that.
It also fixes a bug in auth_finder.pl plugin when summary contains
fields other than 2XX.

Test plan:
0/ You must use a UNIMARC setup for those tests
1/ edit an authority type summary with:
     NP : [200a][, 200b][ 200d][-- 152b --][ ; 200c][ (200f)] [001*] [ppn: 009*]
2/ create a new authority with previous fields (it is possible some
   fields don't exist).
3/ search this authority and verify the summary is someting like:
     NP : Name, D.-- NP -- 23849 ppn: my_ppn
4/ Verify some summary for existing authorities and check they are
   correct.
5/ Edit a biblio record and use the plugin auth_finder.pl (for example
   in a 7XX field)
6/ Do a search and verify the summary is correct
7/ Click on 'choose' or one of the numbered links ('1', '2', ... ; you
should have multiple 2XX fields for the numbered links to show up)
8/ Verify that the biblio field is correctly filled.

/!\ For the ppn, it should be defined in the zebra indexes.

In MARC21 and NORMARC setups, this patch should change nothing, please
verify that too (you can check that the auth_finder.pl plugin is still
working and the auth type summary is correctly displayed in authorities
search and auth_finder.pl plugin).

It works as described, both in authority search result page, and in authority
data entry plugin.

Could add some feature : Migrating from a typecode to an other for instance.
Then we should add some new parameter : bibliotargettag, authtargettag

Get the tag and subfield used to store the heading type
for indexing purposes. The C<$auth_type> parameter is
optional; if it is not supplied, assume ''.
This routine searches the MARC authority framework
for the tag and subfield whose kohafield is
C<auth_header.authtypecode>; if no such field is
defined in the framework, default to the hardcoded value
specific to the MARC format.
