Subject: [PATCH] fix: TestAsyncTransport_SendEnvelope flakiness

The queue overflow testcase was using an unbuffered channel for
RequestReceived, to block the worker so that no other events get
consumed and the overflow will be guaranteed. The channel however was
unbuffered, so the requestReceived (worker) could race with the test and
block the main routine till timeout
