Bug 22849: Do not share data (Mana) without agreement

A couple of things wrong in serials/subscription-add.pl

1.
447     if ( defined( $query->param('mana_id') ) ) {

It's always defined, you wanted to test with ""

2.
375     if ( (C4::Context->preference('Mana')) and ( grep { $_ eq "subscription" } split(/,/, C4::Context->preference('AutoShareWithMana'))) ){

Mana == 2 == let me think about it
=> I am not expecting to reach Koha::SharedContent in that case

So we are sharing data whereas the library did not decide yet!

Test plan:
You need to be familiar you Mana to test this patch.

JD: I did not test this patch
