Subject: [PATCH] finance/statement: make allowance_to optional

If an excursion has zero admissable youth leaders, the statement and hence the excursion
currently can't be saved, because the `allowance_to` field has to be non-empty, but
the number of entries has to be zero. This commit hence makes the field optional.
