xeth: added a transact mu 

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.
