Bug 9006: Remove AUTOLOAD in C4::Context

Bug 9006: Remove AUTOLOAD in C4::Context

Happily this was only used for intranetdir.
It's time to remove it and replace existing calls.

I used the following commands to catch calls to C4::Context:
git grep 'C4::Context\->' | grep -v 'C4::Context->preference' | grep -v
'C4::Context->config' | grep -v  'C4::Context->userenv' | grep -v
'C4::Context->IsSuperLibrarian' | grep -v 'C4::Context->dbh' | grep -v
'C4::Context->set_preference' | grep -v '_syspref_cache' | grep -v
_userenv | grep -v 'C4::Context->interface' | grep -v
'C4::Context->Zconn' | grep -v 'C4::Context->queryparser' | grep -v
'C4::Context->tz' | grep -v 'C4::Context->boolean_preference' | grep -v
'C4::Context->memcached'

NOTE: I applied 14428, and then did what I suggested in comment #2.
      Only intranetdir references appeared.

      I applied this patch, and repeated.
      Nothing appeared. This means the autoload references are
      properly removed.

      koha qa test tools complained about whitespace, I just fixed
      those. Though, we may wish to perltidy
      auth_fields_substructure.pl on another bug.
