Subject: [PATCH] NonceManager: fix transaction count update when sending
 transaction

This commit fixes an issue that leads to reused nonces in some cases.

When passing a transaction with a defined nonce, the NonceManager uses that to set the transaction count, which leads to the same nonce being reused for the next transaction (if the nonce is `n`, there has been `n+1` transactions)
