Bug: Unhandled exception after using Nuix

Summary

After using Nuix with EDR the following message is shown

2021/02/18 17:37:47.427 Export complete.
Unhandled exception. System.InvalidOperationException: No process is associated with this object.
   at System.Diagnostics.Process.EnsureState(State state)
   at System.Diagnostics.Process.get_HasExited()
   at Reductech.EDR.Core.ExternalProcesses.ExternalProcessRunner.<>c__DisplayClass4_0.<StartExternalProcess>g__KillProcess|0(Object sender, EventArgs e)
   at System.AppContext.OnProcessExit()

This is perhaps caused by the process being disposed at the wrong time.
