Remove Windows service workaround

[spaceisfun]

Issue is due to dotnet/runtime#50020

Workaround is documented in issue above, but requires a fork of behavior between Windows Service and Windows applications (likely by checking for an extra argument passed in to the service mode)

Workaround is now implemented in #139, commit 51c113e. This issue tracks reverting it once there is an official fix.
