StopAsync immediately after StartAsync fails #75
Description
When on the FTP server the method StopAsync is called immediately after StartAsync, the method fails with the following exception:
---> (Inner Exception #0) System.InvalidOperationException: Status must be Running, Stopped, or Paused, but was ReadyToRun.
at FubarDev.FtpServer.Networking.PausableFtpService.<StopAsync>d__19.MoveNext()
--- End of stack trace from previous location where exception was thrown ---

at System.Runtime.CompilerServices.ConfiguredTaskAwaitable.ConfiguredTaskAwaiter.GetResult()
at FubarDev.FtpServer.FtpServer.<StopAsync>d__36.MoveNext()<---
In my opinion, it should also be possible to stop the FTP server in state "ReadyToRun".
The same issue occurs also when calling PauseAsync immediately after StartAsync.
