Version information:

• OS: Windows
• PactNet Version: 5.0.0-beta.3

Describe the bug
We're seeing intermittent issues, both locally and in CI, on Windows whereby the messaging provider fails to start, with the error:

PactNet.Exceptions.PactFailureException : Unable to start the internal messaging server
---- System.Net.HttpListenerException : The process cannot access the file because it is being used by another process
  Stack Trace:

Steps To Reproduce
Intermittently happens when running messaging tests

Expected behavior
The messaging server finds a free port and starts successfully
