TestResults folder shouldn't be created for help request

[MaceWindu]

Describe the bug

Running help command:

mytests.exe --help

creates TestResults sub-folder in test application folder.

Steps To Reproduce

mytests.exe --help

Expected behavior

No changes to environment expected (we use different location for actual results folder)

Actual behavior

TestResults folder created

Workaround

Pass unknown parameter instead of help:

mytests.exe --welp

Same help printed, but no folder created.

Maybe we should wrap this call in if (commandLineHandler.IsHelpInvoked())

testfx/src/Platform/Microsoft.Testing.Platform/Hosts/TestHostBuilder.cs

Line 278 in 0b16e9e

await configuration.CheckTestResultsDirectoryOverrideAndCreateItAsync(loggingState.FileLoggerProvider).ConfigureAwait(false);
