Added a transact mutex. The transact mutex will fix an issue where transactions were created with the same nonce resulting in some transactions being dropped. This happened when two concurrent calls would call the `Transact` method (which is OK) which would both call `GetNonce`. While the managed is thread safe it does not help us in this case.
