TestAsyncTelemetryHook_Close must be removed

[algonautshant]

Summary

TestAsyncTelemetryHook_Close and TestAsyncTelemetryHook_QueueDepth in logging/telemetryhook_test.go were likely disabled since forever.

It uses a mock telemetry hook, but the code expects a telemetryFilteredHook in createAsyncHookLevels to change the hook to ready, so that the hook's Fire gets called.
However, the conversion of wrappedHook from go-algorand/logging.mockTelemetryHook is failing.

Scope/Requirements

This tests needs to be removed.

Urgency/Relative Priority

Not a high priority, since this was disables forever.
