ValueError: StatsEntry.use_response_times_cache must be set to True

See original GitHub issue

I see this on every locust worker running 1.2:

$ locust --worker --locustfile=main.py

Tried with very basic locust file, same issue:

from locust import HttpUser, TaskSet, task, between

class LoadTestTask(TaskSet):
    def on_start(self):
        pass

    @task(3)
    def get_token(self):
        pass

class LoadTest(HttpUser):
    tasks = [LoadTestTask]
    wait_time = between(0.1, 1)

Any idea @cyberw or @vstepanov-lohika-tix?
