These tests relied on some timing for file writes and static property access. This replaces that with a TaskCompletionSource as well as uses the HttpContext.Current for the static access so it can't have race conditions.

Left a couple of very small nitpicks but looks great otherwise. Thanks for the fast turnaround @twsouthwick, hopefully we can get this in sooner rather than later so that we can push the packages to NuGet.

These tests relied on some timing for file writes and static property access. This causes a race condition where the change monitor is disposed at some point internally, but at the same time the test tries to dispose it. This causes the list of change monitors to be enumerated/modified at the same time leading to a crash. The following are fixes/mitigations:
This also changed the IHttpRuntime access to go through HttpContext.Current instead of a static property. While not necessary for the current bug, it has been the source of other issues where a test will set the static property at the same time another test is using it. Switching to HttpContext.Current will prevent similar issues as the IHttpRuntime will be request/test local.
