Be more defensive in BufferingDisabled test (#12278)

Fixes https://github.com/aspnet/AspNetCore-Internal/issues/2826 We [use `?.` in `master`](https://github.com/aspnet/AspNetCore/blob/f56cb72b7fa01ea09c3d3b128aaeb9cee937b371/src/Hosting/Server.IntegrationTesting/src/Deployers/ApplicationDeployer.cs#L103) and it seems like the test can end up in this state (by the linked issue) so back-porting that defensive measure seems reasonable.
