Bug 21915: Call reconcile_balance on manual credit creation

This patch makes the manual credit creation step call
Koha::Account::reconcile_balance when the AccountAutoReconcile syspref
is set.

To test:
- Apply the patch
- Have some outstanding debits
- Create a manual credit
=> SUCCESS: Same behaviour as always
- Set AccountAutoReconcile
- Create a manual credit
=> SUCCESS: Reconcillation happened
- Sign off :-D
