Bug 4114 - netconf connector replace causes transaction chain failure
In order to avoid race condition when txChain perform delete then write
transactions in a row to the same path, perfom the delete as a blocking
transaction so once done, write can be perform without any race condition
Also reset the txChain after a failure.
