issueToken: add separate function for vault to claim collateral/fee for failed issue commitments #15

Cheap: vault tracks all emitted events and submits the expired commit ids - but vault must be online. Alternative/additionally: vault calls claimAllFailed function, which checks all failed or expired commitments

In any case: add getAllExpiredCommitments(address vaultAddress) which returns all expired commitments for each vault (off chain)
