Subject: [PATCH] Bug 20447: (follow-up) Add required metadata field when
 creating holdings

Since metadata column is mandatory in the holdings_metadata table we
need to define it already when it is first created instead of creating it
first and updating the column immediately after.

This fixes the following error during holdings record creation:
DBIx::Class::Storage::DBI::_dbh_execute(): Field 'metadata' doesn't have a default value at /kohadevbox/koha/Koha/Objects.pm line 114
