Description of changes
This change ensures that goroutines that were lingering/leaking are cleared once the test ends. This change focuses on the goroutines that were highlighted when trying to create e2e tests for the change in grafana/k6#3235. There could be more goroutines that are lingering/leaking that we need to deal with in the future.
Closes: #989
