Transient failure of TestStopBufferingAndDiscard in the CI pipeline

[Bartleby2718]

This failures very often in the CI pipeline (e.g. https://ci.appveyor.com/project/madelson/medallionshell/builds/49368379/job/5y4a5w70cght8ksd):

Failed TestStopBufferingAndDiscard [3 s] Error Message: can finish after read (state=0, linesWritten=144) Expected: True But was: False Stack Trace: at Medallion.Shell.Tests.GeneralTest.TestStopBufferingAndDiscard() in C:\projects\medallionshell\MedallionShell.Tests\GeneralTest.cs:line 284

1. at Medallion.Shell.Tests.GeneralTest.TestStopBufferingAndDiscard() in C:\projects\medallionshell\MedallionShell.Tests\GeneralTest.cs:line 284

FWIW, when I ran only that test alone consecutively locally, it passed 20+ times without any failures.

Seems like this was a known issue per https://github.com/madelson/MedallionShell/commit/aa09a7fd66cd0bb2ffa76ba911db8c632e7027ab
