Facilitator is fails to confirm some of the messages if the on chain status of message is not known.

Following is the test scenario:
Account A tries deposit token (outboxNonce is x) on the origin chain.
The facilitator is down. The confirm deposit is not done on the metachain.
The facilitator is up and running now.
Account A does the deposit again (outboxNonce is x+1) on the origin chain.
The facilitator get the depositIntentDeclare entity, and with all the flow it tries to confirm the deposit.
In this case, the transaction will fail, because the inboxNonce on ERC20Cogateway is still x
This will happen for withdraw flow too.
