Make tests less flaky (#194) 

# Motivation
After the recent changes in NIO where we introduced the `executeThenClose` method on the `NIOAsyncChannel` our tests here became flaky since we were waiting for something to happen but potentially closed the client channels before we wrote out the data.

# Modification
This PR makes sure we are awaiting for the event in the `executeThenClose` scope; hence, making sure we are not closing the client channels too early.

# Result
Less flakey tests.
